Pet Sitter

I need a pet sitter for my planned weekend trip starting 09/18 (and for a few more similar trips throughout the year) to check on, feed, and provide fresh water for 4 healthy adult cats in Tucson, which would involve 3 visits per day for feeding and fresh water, and adding scooping their litter boxes to the last visit each day. It's also very important to spend some time with them each visit so they become completely comfortable with their sitter. Proximity to my 85730 area code is highly preferred, as I understand the sporadic nature of the schedule. We can work out a fair payment arrangement for multiple visits/day.
