My 7 year old tabby boy had lost 2 lbs over past 2 months. He is acting perfectly normal eating, drinking, voiding and playing normally. The vet check was all good labs and stool smear normal. Since he actually needed to lose weight he is still over 12 lbs the vet is not concerned. But what could csuse him ti spontaneously loss 2 lbs? Anyone have a similar experience with a kitty? We did move could it be stress??
