Why is my newly adopted cat not eating and missing the litter box?

It's actually quite serious that Tigger isn't eating. When cats go for 72 hours without eating, they develop a fatty liver. A fatty liver is fatal without treatment. While it could be he is stressed from the move to his new home, it could be a medical illness causing him to not eat. He should see a vet immediately for a health check to prevent him from developing a fatty liver. Best of luck.

I would recommend bringing Maomao to the veterinarian to have him evaluated. I would let the veterinarian take a urine sample to make sure there is no urinary tract infection especially if he is urinating outside the litter box. This is a concern that I have when cats urinate outside the litter box especially if goes into the litter box and then comes back out. Thank you for using Petco Pet Education Center, formerly Petcoach.

Congrats on your new cat! You are correct that Oliver should stay inside for a while since he has moved to a new home, good on you for doing that! It is a little concerning that it's been 36 hours with no eating or going to the litter box, but moving into a new home is stressful. Because cats can develop a fatty liver when they haven't eaten for three days or more, which is fatal without treatment, I'm going to give you some things to try to tempt him to eat. You can soak his food in gently warmed low sodium beef or chicken broth, or soak it in tuna juice. You can also try offering him small amounts of boiled white meat chicken (no bones). If you can get him to eat, then he will use the litter box. Should he still not be eating in the morning, then I would take him into the vet for a health check just to be safe. Hopefully, however he will eat some of the tasty morsels I've suggested you give him :-)

Poor Cathy! Not eating is quite serious in cats, as when they go long enough without eating, they will develop a fatty liver. A fatty liver is fatal without treatment. She may not be eating because she has a dental problem, systemic illness, infection, inflammation, or injury. Please take her into a vet now. Best of luck.

A cat that has not eaten for 3+ days is at serious risk of developing liver related complications. This could compound any underlying condition. Itis important to have Minnu examined by your veterinarian today to diagnose and treat the cause. Supportive care (hospitalization, IV fluids, antibiotics, appetite stimulants, etc.) may be indicated until Minnu recovers and is eating regularly.

Missy has to see a vet as soon as possible. When a cat doesn't eat for three days, they develop a fatty liver which is fatal without treatment. She needs to see a vet now to prevent that from happening. In a senior cat like Missy, her anorexia could be caused by kidney failure, cancer, diabetes, and liver failure among other causes. It's also serious that she hasn't used the litter box in two days. She needs a physical exam, geriatric blood panel, and urinalysis to diagnose what is causing her symptoms so she can be treated.

It is a medical emergency that Romeo hasn't eaten in five days. When cats do not eat for 72 hours and longer, they will develop a fatty liver, which is fatal without treatment. He may have severe dental disease or an illness causing his bad breath. He has to see a vet now, please take him into one immediately.
