Cat Sit My Princes! 8 Yo Gray Long Hair, 9 Mo Black Short Hair

Steven and Cosmo Steven (8 yrs) is sweet and aloof. He likes to sleep in the bathtub and enjoys his kick-toys, dusted with cat nip. Cosmo (9 mos) is young, playful and affectionate. He looks forward to play time just as much as breakfast and dinner. Dry food is dispensed automatically. I add 1/2 cap of dental additive to their water bowl, which is changed every other day. Both cats get 1 scoop of Viralys with wet food, twice daily, around 7 a.m. and 5:30 p.m. They have 3 litter boxes that need to be scooped/cleaned every morning. They haven't been around very many other animals. The one dog they know well is a 14 yrs, 20lbs, rat-terrier mix. There are parking spots available in front of my building..
