My cat is isolating, lying on floor, and peeing less. Is he sick?

Most cats become very inactive during hard summer, it's absolutely normal, as long as he has a cool surface to lay on and plenty of shade he should be fine. if you have a fan at home it can help but not all cats tolerate fans.

That sounds worrisome that she is either not producing urine or that she is unable to urinate. Both of these conditions are serious. I recommend to play it safe and to have Layla examined today. You may need to get her in with another clinic or even an emergency clinic. The doctor will need to palpate her bladder and run bloodwork and a urinalysis. It's best to play it safe. I hope she gets better quickly. Please feel free to post any additional questions.

These symptoms are definitely of concern and most likely a sign of illness and not depression. It is not any fault of yours, but he does need to see a veterinarian to determine the cause of his illness. They may recommend running bloodwork to check for signs of systemic illness such as kidney disease or infection, and may want to test his for Feline Leukemia and Feline Aids since he was an outdoor cat before he came to you.

I'm sorry your kitty isn't eating as much right now. It could be because it's so hot in Australia that his appetite has decreased, or it could be that he has a dental problem or illness causing his decrease in appetite. It's always best to have a health check done by a vet when a cat stops eating as much, and I would have him seen by a vet either today or tomorrow. If there is a medical cause behind his lack of eating, the vet can treat him for it.

I’m so sorry to hear about Tommy! It sounds like he could have an infection, kidney disease, or a host of other possible ailments. Any kitty who has been acting this way for 3 days needs to see the vet sooner rather than later. Your vet will likely recommend some bloodwork to help determine what is wrong and offer some treatments to help him feel better. Best of luck to you and Tommy!

It sounds like he should be examined by a vet to rule out a medical problem. He could have an infection, parasite, metabolic, and/or endocrine disease and your vet can run blood work to help diagnose and the determine if treatment is needed. Hope he feels better soon!

Sometimes a cat will hide in an unusual location simply because they are not feeling well. He may feel that getting wet is worth it if he feels safer in the bathroom. Given that he has been sick for a few days and he is not eating, I would recommend that you have him seen by a veterinarian. Cats that don't eat for even more than a few days can become quite ill very quickly. In the meantime, I would try to keep him as dry as possible. Perhaps provide a box or bed in the bathroom to see if he would use it rather than the area that he is getting wet in
