My cat (4 yr old domestic) has recently been snubbing his dry food (Hill’s Urinary Health). He’ll eat a little, but will mostly ignore it and beg for wet food for most of the day. (They both get wet for dinner.) This has been going on for about 2-3 weeks. I worried his mouth or teeth were hurting him, but he doesn’t seem to have issues eating wet food. Both of my cats seem hungrier than usual – is that just because it’s gotten colder? Or because I’m now home all the time? How do I know if he is just being fussy or if there is a larger health issue?
