I am sorry to hear about Annabelle. If she is not eating and now not drinking these are definitely signs of concern that require evaluation by a veterinarian. In particular, if she is an overweight cat (it says on your information that she is 14 pounds) then she is at risk of developing a dangerous liver condition called hepatic lipidosis if she isn't eating. There are many possible underlying causes for her symptoms, including primary GI disease (such as inflammatory bowel disease, gastritis, stomach ulcer, gi tumors, gi infection, pancreatitis, cholangiohepatitis) or disease of the liver or kidney (either of these can cause increased thirst). The vet will want to do an examination and will likely recommend bloodwork and an x-ray to try to determine the cause of her symptoms. She may need to be prescribed an appetite stimulant, and may need fluid therapy if she is dehydrated.

Hello, thank you for your question about Chloe. Lack of appetite, weight loss, and increased thirst can be signs of many different underlying problems such as diabetes, GI disease, or a thyroid problem. I would recommend having her seen by a veterinarian so that they can examine her and discuss performing bloodwork to look for an underlying problem. Hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! How old is your cat? From the picture she looks a bit sick. If she can not poop she may be constipated. Constipation is a symptom of something else either kidney disease or intestinal disease. Since she isn't eating well and is drinking a lot, I recommend a Veterinary exam and full blood work. Causes of increased thirst are: kidney failure, liver disease, diabetes, cancer, hyperthyroidism (over active thyroid). I hope this helps and I wish you both the best!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your question. I would recommend having her blood tested to ensure there are no abnormalities such as thyroid disease or diabetes. I would speak with the veterinarian again and see if you can bring her in to have her blood drawn and tested to rule out other causes. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
