I have 1 cat, an 8yr female medium-hair tabby & white cat called Bibby, & 2 guinea pigs, called Holly & Tilly. I would have more animals if I could.
I come from a farm where we had all sorts of animals - horses, dogs, cats, chooks, cows & calves, bulls, sheep, guinea pigs, rabbits...
I've just realised your cat is a kitten. Sorry.
I still wouldn't leave both the wet & dry down together. Follow the previous suggestions, but put the dry down between the wet meals & for night time to snack on. Get the best quality dry food you can afford - there are other brands besides Orijen...
