This is my first time ever owning a cat, I’ve only ever fostered strays, and it’s my first pet I’ve owned on my own, I’m 22. I found him by my garage, and he’s been cleared of parasites and neutered now. I give him the dry food Purina LiveClear for kittens, since he’s still under a year old according to my vet. I want to try getting him on wet food on occasion so he doesn’t develop any urinary issues, but the Fancy Feast grilled is what I bought and it upsets his stomach. He has a water fountain that he drinks from. I have some probiotic powders I can give him sometimes, I give him L-lysine treats every day per vet instructions, a calming treat at night since he’s young and rowdy and I need to sleep sometimes, and the occasional greenie treat or a dried salmon and cod treat. Should I buy him some fish oil for his food? Does he need any extras? I want him to be as happy and healthy as possible.
