Hi Jax, the combo is okay, especially if the main intake is the wet, but all wet would really be best and more especially, it seems, if you have male cats
. The crystals seem to form in
more than females, at least, that's been the experience here on the forum and what my vet told me, also. Someone, please correct me if I'm wrong.
Just a tip, Jax...cats are lactose intolerant and milk will upset their tummy and possibly cause diarrhea. Just water would be best.
