My 10 year old Calico cat is not feeling quite herself for the last 3 days now. She is lethargic and barely eating any food. She is still drinking plenty of water and does not appear to be in any pain. She has also not had any bowel movement in a few days as well. I am going to take her to the vet on Sunday if she hasn’t improved by morning. She is exclusively an indoor only pet and does not have contact with any other cats. She is current on all vaccinations and has no history of any health aliments.

Any ideas?? Thank you!!

I'm glad your going to take her to the vet. My feeling is when a animals stops eating there is a problem. Please post back and let us know how she is.
As for the pain cats do not normally show pain. Most of the time they will shy away from people or other animals.

Kitty is better... she had 3 massive furballs in the lower intestine... had an enema today... lets say that she it 110% of normal back to her old self!! Thanks you for your support!!

A very happy kitty owner!
