Cat stopped purring
I have an older female siamese cat (17). She has been in relatively good health but is now on pills for irritable bowel disease, and taking an appetite stimulant. About 2 months ago she stopped purring loudly. If I put my ear to her belly I can still hear her purring, but it is no where near the volume she formerly had. Is this normal? She still exhibits all of her old habits, but is now using the bathroom on the floor occasionally when she has diarrhea.
