Maple is approximately 1 year old. She was a stray who had a litter of 9 in our garage on Mother's Day. We brought all of them inside to keep them safe and found homes for the babies. Soon after, we began fostering 2 neonate kittens, both boys. She mothered them, too, but does not get along with our female adult cat and it's stressing the entire household. She minds her business around our 2 dogs.
