Our cat had been listless for a week or so, wife took her to the vet today and they said she had a mass on her stomach that was the issue. She was a stray that showed up here 8 years ago out of the cornfield. Part Maine Coon she was a constant companion for my kids when they were outside, hung with me in the garage and even befriended our new puppy. Great cat, much loved; sleep well Kylie.
