Hello! My guys (or gal, not sure of the sex) has been acting a little on the hormonal side with a heavy emphasis on the regurgitation, theyve been playing and chatting as normal but the last day or so hasn't been eating much. They'll eat some blue berries but has gone completely off their kibble (ZUPREEM fruit blend). Could the appetite change be related to hormones? We went to the vet 2 months ago for this and my guy came up clean. But I noticed the last time seemed to coincide with more hormonal kinds of behavior. Putting them to be a little earlier seemed to be the fix weirdly enough. Any help would be greatly appreciated!
