So my cat is only a year and a half old, and he got crystals. He has been on just the wet Urinary S0 for about a month and a half now. The food is just way out of budget for me (student, work only 4 months a year) , however so is going back to the vet if there is a recurrence. I see that there is Urinary S0 dry, however I'm curious if I keep feeding him the Urinary S0 wet (say 1/2 can for breakfast) can I feed him another dry food rather that the specialty one? I have no preference on brand, this is my first cat and really I know nothing about what brands are good unless we're talking dogs. Any help would be appreciated!
