My two 2 year olds eat wet and dry.
Vet found that one of them has bad gingivitis, which could cause early tooth issues, so recommended Hill's Prescription t/d Dental food. The other (super finicky) cat also likes it, so I give it to both of them.
Wet, they like Applaws Tender Chicken Breast in Broth. Again, one is super finicky. He likes it, and it doesn't have preservatives, ash, or other additives.
Both are slighly more expensive than other foods, but I don't have kids, so I might as spoil the furkids!
