Cat Sitter During Vacation

Assortment of cats need care while I am on vacation beginning September 19th. Three have the run of the house. They have three feeding stations. Share two litter boxes. Boxes MUST be cleaned daily as one cat is diabetic and consequently passes a good deal of urine. I am socializing a feral kitten who currently is housed in the bathroom. She is 4-5 months old. Not fond of being handled but loves to chase balls. She has her own feeding station and litter box. The kitten's feral mother is accustomed to finding dry cat food and water on my back porch. I'm hoping she too will become an indoor cat. The kitten has already been neutered and received her first shots.
