I have five cats posted before. One got a urinary blockage was on special food but weaned him off to wet friskies with lots of water. Have three other boy cats inside and a female outside. Just weaned all them off hard and on too moist with lots of water. Seems to be upsetting ones tummy but not sure which one. Really mushy poos. And like they almost didnt make it to box. Sorry. Male cats inside range from 8 momths to 3 yrs old.
