Although cats tend to be solitary, being a pet owner means you know what their normal behaviour is like. And although a cat's temperament may vary from one pet owner to another, there are a few common behavioural and personality changes that likely mean that your pet's health has become compromised. If you do not know what to look for, here are some sudden changes in your cat that should have you rushing them to a veterinary hospital.

A drastic change in personality

Personality changes can manifest in various ways. For instance, if your pet is usually quite even-tempered and likes to have a cuddle occasionally, sudden aggression can mean that they do not want to be touched because they are in pain. On the other hand, a previously temperamental cat that is suddenly in constant need of attention could mean your cat is seeking comfort from a health issue you are unaware of. While personality changes are subjective, it is still advisable to stay on the safe side and have your vet have a look at your cat.

Changes in appetite or water intake

When your cat's feeding habits change, there is a possibility that they are afflicted with a health problem. Usually, when cats are sick, they will eat less than usual. Therefore, if you are continually finding their cat food untouched, you should be wary of a health issue. However, it should also be noted that some illnesses, such as diabetes and hyperthyroidism, can result in a dramatic increase in appetite. So it is vital to monitor this, too. In addition to their food intake, you should also note how much water they are drinking too since kidney diseases could have an impact on their consumption.

Irregular bowel movements

If you have had your cat for several months or longer, you probably know what frequency to change their litter box. So if you find that this frequency has become more or less, then your pet could be having irregular bowel movements. Many illnesses could cause a change in your cat's bowel movements, including bladder problems, kidney infections, anxiety or even dementia if your cat is of a certain age.

Unusual vocalisation

Another behavioural change in your cat that should prompt you to see a vet is a change in their vocalisation. Some of the changes that usually indicate that your child is in pain are incessant meowing, sudden caterwauling or even unexplainable growling. While behaviour modification may be your first instinct, it is worthwhile to get your vet's opinion first.
