I have been fostering cats for more than 8 years. I currently have a 9 months old female kitten at home, fully vaccinated with rabbis and FVRCP. I only take ONE CAT at a time. I am a school teacher so I am off after 3 pm from Monday to Friday. I am home after work and mostly home on weekends. We use litter robot at home that promises forever clean pot ! Cat tree and various cat toys. I only take ONE CAT at a time. Your cat will run around the apartment with only my cat. All windows are protected and closed. I have surveillance camera in the apartment to monitor when I am away.
