Then her appetite decreased for 3 days, she got a stuffy nose and sneezing,drink a lot and sat by the bowl( maybe because of her cold),then diarrhea. For over a week she is eating with no problem, more than usual. Her canned food has not changed. 7 yrs old 7.9 pds- gained a few oz from eating like a normal cat . Still sneezing a little. Haven't seen her use the litter box but the vet said her Blatter was empty and said she was fine after doing a physical exam. She no longer sits by the water.What is weird is she no longer throws up or lethargic in the morning, has anyone dealt with this? I am baffled.
