Reply to Terri Riba's Post: We feed her Meow Mix (the same as our cats) and she eats like a horse, she actually adopted us. She came with our house and we do not let her in because we have two other cats. If I had to guess I would say a year maybe two. She is energetic, and doesn't seem ill. She does get into fights but there doesn't look to be any trauma. Our other cats are healthy.
