Our yellow male is 8 years old..recently diagnosed with feline leukemia. what is the best product for acid reflex? Had cat eat "recovery" canned food, started drooling and vomiting. Has had acid reflex before assume he has it now. He's a feline leukemia victim and won't eat hence the recovery food that has been syringe feed (awful). Any suggestions for acid and eating? Thank you so much.
