Common cat behavioral issues – Diet & Treatment Advice

Cat behavioral issues are persistent patterns of behavior, such as aggression, destructive scratching, or litter box avoidance, that fall outside a cat’s normal behavior and often signal an underlying physical or emotional problem. Cats, like humans, experience a wide range of emotions that can directly affect the way they behave.

When a cat starts “acting out” this is generally a sign that something is not quite right in their world, physically and/or psychologically.

Anybody who has lived with a misbehaving cat will tell you how much of a handful they can be, but it is always worth remembering that persistent bad behavior will typically have an underlying cause.

Cat behavior problems are extremely common. For some felines an uncharacteristic change in mood may only last a few minutes. For others it may continue for weeks.

Early intervention can prevent the latter from occurring and should hopefully set your feline on a path to better behavior.

What causes behavioral issues in cats?

Here are a few possible reasons:

• Medical condition. Behavioral issues are sometimes indicative of a much larger problem. A cat in severe discomfort is almost always going to act differently to how they usually would. Pain from arthritis, dental disease, or urinary tract infections can trigger aggression, hiding, or litter box avoidance. If you believe your cat is experiencing pain or is suffering from illness, seek medical assistance immediately.
• Stress. Stress is known to be a significant trigger for cat behavior problems. Cats are creatures of habit, and disruptions to their sense of security can manifest as destructive behavior, excessive vocalization, or withdrawal. It can be difficult to spot when a cat is stressed, but a change in behavior is definitely one of the signs. Common cat stressors include moving homes, separation anxiety, and introduction of another pet.
• Change in routine. Cats do not like their routines being disrupted. Even small changes, like a new work schedule or rearranged furniture, can unsettle a sensitive cat. Try and keep their schedule (feeding, grooming, playtime) consistent. If you do need to change things around, do so gradually over 7-10 days, giving your cat time to adjust.
• Poor diet. A diet lacking essential nutrients can lead to low energy, irritability, and health problems that affect behavior. Feeding your feline a high-quality diet – one that is packed full of body-boosting nutrients – will help keep them fit, full and happy.
• Boredom. A cat who is not receiving enough mental or physical stimulation may become increasingly frustrated. Without adequate enrichment, cats may redirect their energy into destructive or attention-seeking behaviors. Make sure you provide them with plenty of toys, schedule regular play and grooming sessions, and ensure they are keeping active.

Common signs of behavioral issues in cats

• Destructive behavior with household items. Cats are naturally curious and playful, so it’s not unusual for them to occasionally scratch or chew things around the house. However, repeated destruction of household items needs to be addressed promptly. When scratching becomes obsessive or targets multiple items daily, it typically indicates stress, territorial anxiety, or insufficient scratching outlets. Carpets, couches, curtains, doors, windows; few items are safe when a cat begins acting out in a destructive manner. Place one or two scratching posts around the house and give their nails a trim while you get to the bottom of their bad behavior.
• Aggression to humans or other animals. Acting aggressively towards humans or other cats is not normal behavior for a feline. The odd altercation is nothing to be concerned about, but continued displays of aggression, especially if unprovoked or escalating in intensity, are a sure sign something is bothering your cat. A number of reasons could be behind these feline flare ups. Ruling out pain and discomfort is a good place to start, so you’re best speaking to a vet first before taking any further action. Never punish your cat for aggressive behavior, it will only make the problem worse.
• Litter box rejection. A common behavioral issue exhibited by cats is litter box avoidance. While frustrating for pet parents, it also isn’t nice for cats, either. Occasional accidents may happen, but if your cat consistently avoids the litter box for more than a few days, it signals a problem requiring attention. Cats suffering from separation anxiety tend to struggle with uncontrollable urination. Resolving this problem quickly is vital if you don’t want it to become a habit. It may be that they have an aversion to that particular litter box. Make sure you clean it out regularly. If that doesn’t do the trick, then try placing it in a different part of the house. Or better yet, provide them with a number of boxes so they can choose where they would like to go.
• Excessive grooming. Cats are proficient self-groomers. It’s how they keep themselves clean, how they regulate their body temperature and how they cleanse any injuries. Felines can sometimes take grooming too far though, resulting in bald patches or sore areas of skin (commonly on their stomach or legs). Normal grooming becomes problematic when it leads to hair loss, skin irritation, or occupies a significant portion of your cat’s waking hours. The excessive licking is generally triggered by a change in routine or their environment, although skin allergies and parasites are possibilities that should also be considered.
• Increased vocalization. The amount of meowing a cat does will vary from breed to breed and may also change as they grow older. Stressed cats do tend to be more vocal, while others will cry or whine because they want attention. A sudden increase in vocalization — particularly yowling at night or persistent crying — often indicates distress, pain, or cognitive changes in older cats. Only give them attention when they are silent, otherwise they may begin crying all the time. Don’t ignore the meowing though, no matter how persistent it may be; not until you have checked there isn’t a problem. Hunger or pain can bring about excessive meowing so you will certainly want to rule those out.
• Stealing food. Cats are born hunters so helping themselves to food is not completely out of character. Despite this, it is a habit you will want to nip in the bud sooner rather than later. Stealing food from the table or the counter may be extremely annoying for a pet parent, but it’s potentially lethal for a feline. Do not feed your cat scraps from the table as this will only encourage the behavior. Focus on their diet. Are they enjoying their food? Are you packing their diet with enough nutrients to keep them satiated?
• Up all night. Cats will spend most of their day sleeping. In fact, many felines will spend at least 16 hours a day snoozing. All this built-up energy means they can end up running around the house at night, making noise, looking for somebody to play with. While felines are classed as nocturnal, they’re actually crepuscular which mean they tend to be most active during dusk and dawn hours. Try and train your cat to follow a sleep pattern. Play with them before bedtime and ensure they are well fed. This should ensure they sleep through the night and allow you to do the same.

How to treat behavioral issues

There’s no one-size-fits-all solution when it comes to cat behavioral problems.

All felines are different, each with their own distinct personality, which can make diagnosing and treating a change in attitude particularly difficult.

Thankfully, the majority of behavioral issues can be resolved without need for professional intervention.

Follow this step-by-step approach to address your cat’s behavioral issues:

Step 1: Rule out medical causes. Schedule a veterinary examination to ensure pain, illness, or discomfort isn’t driving the behavior. Many behavioral changes have underlying health causes.

Step 2: Identify environmental stressors. Look for recent changes in your cat’s environment—new pets, moved furniture, schedule changes, or household disruptions that may be triggering stress.

Step 3: Adjust diet and routine. Ensure your cat is eating a high-quality, nutrient-rich diet and maintain consistent feeding, play, and sleep schedules.

Step 4: Increase enrichment. Provide adequate mental and physical stimulation through interactive toys, scratching posts, climbing structures, and regular play sessions.

Step 5: Implement gradual changes. If modifications to your cat’s environment or routine are necessary, introduce them slowly over 7-10 days to minimize stress.

It’s worth noting that you’re not going to correct a cat’s behavior overnight. If destructive behavior or aggression persists for more than two weeks despite your interventions, consider seeking professional guidance.

Do not lose patience with them, no matter how infuriating their conduct has become.

Shouting at a cat or punishing them in some way will only serve to exacerbate the problem.

When to see a veterinarian

Seek professional veterinary advice if your cat exhibits any of the following:

• Sudden aggression, especially if unprovoked or directed at family members
• Persistent litter box avoidance lasting more than a few days
• Dramatic changes in appetite — either refusing food or eating excessively
• Excessive grooming resulting in bald patches or skin wounds
• Sudden behavioral changes accompanied by lethargy, vomiting, or other physical symptoms
• Behaviors that pose a safety risk to your cat, other pets, or family members
• Any behavioral issue that doesn’t improve after 2-3 weeks of consistent intervention

If you believe a change in behavior is related to injury or illness, don’t hesitate to book an appointment with your vet.

Does diet play a part in behavior?

Yes, diet significantly impacts cat behavior. A nutritionally complete diet supports stable energy levels, proper brain function, and overall well-being — all of which directly influence how your cat behaves.

Treating behavior problems in cats does not have to be reactive, there are plenty of measures you can put in place to prevent your felines from acting up.

And there’s no better place to start than diet.

A well fed cat will more often than not be a happy cat.

Felines who are fed inadequate diets, lacking high-quality proteins, vitamins and minerals are more susceptible to the health problems that will inevitably lead to changes in behavior.

Reveal’s recipes – like our Tuna with Sea Bream in Broth, Chicken Breast with Cheese in Broth, and our Tuna with Crab in Broth – all focus on natural ingredients that are not just delicious but healthy, too.

Rewarding good behavior through food is another method that may be worth exploring.

Using our tasty Whole Tuna Loin treats to say “well done” will show your cat that good things follow good behavior.

Frequently Asked Questions

Why is my cat suddenly aggressive? Sudden aggression in cats is often caused by pain, fear, or stress. Medical conditions, territorial disputes, or environmental changes can all trigger aggressive behavior. If aggression appears without warning, consult your veterinarian to rule out underlying health issues.

Can changing my cat’s food cause behavioral problems? Yes, abrupt diet changes can cause digestive upset and stress, potentially leading to behavioral issues. Always transition to new food gradually over 7-10 days by mixing increasing amounts of the new food with the old.

How long does it take to correct a cat’s behavioral problem? Most behavioral issues improve within 2-4 weeks with consistent intervention, though some may take longer. If you don’t see improvement after 2-3 weeks of dedicated effort, consider consulting a veterinarian or animal behaviorist.

Is my cat misbehaving out of spite? No, cats do not act out of spite or revenge. Behavioral issues are always rooted in underlying causes such as stress, medical problems, environmental factors, or unmet needs. Understanding the cause is key to resolving the behavior.
