My two get wet food only and I mix it with water and they pee more than any cats I’ve known. At least twice a day and large quantities. They’re both super healthy - just way more hydrated than the average house cats that eat dry food.
My dog’s poops get a sort of dry consistency when I feed her pumpkin. If it starts binding her up a little I scale back the amount. My cats only get about a quarter teaspoon each - they don’t need much.
I wish I had every other day poopers but mine go twice a day each! Ugh.
I would only be concerned if he stopped eating or peeing or if he seemed otherwise unwell.
