I have known Felix (or Fee Fee) as I call him sometimes, for 16 years. His servant Dennis, made a nice ramp for him to get into his bed, and he sleeps peacefully with his cat buddy, Oliver, also adopted at same time. They are inside cats, (youthful appearance reason?), eat regular cat food, but are showered with love and affection, so they have aged well. Of course, both neutered...Save lives, spay and neuter all your pets!
