Is it wrong that I gave the kitten one gallon of milk at a time?
I don't think a cat can drink a gallon of milk. Can you tell me why you did this?
Well, I wanted my kitten to be very strong and I usually give my dog two gallons of milk per meal.
What you give you dog is irrelevant here, a cat cannot consume that much milk without getting sick. You should research how to take care of a cat before you feed them again.
It's just a kitten, I think it can handle it.
No cat, especially a kitten, is able to drink a gallon of milk at one time. It's wrong to try and make that happen. It's important that you watch a video on Youtube about ways to properly feed a cat.
