Animal Care Needed

Milo is 4 years old and very gentle, We have had him for 2 years. Cosmo is 15 months old and we have ha him for 1 month. He is also very gentle. We got Cosmo because Milo had a hard time being alone. My daughter checks on them when she can, but cant do it 2x day. The 2 kitties seem to get along, but have had occasional scuffles. Both cats are healthy and like to play. They dont need medication, are neutered, and up to date on shots.
