This is a late review but better late than never I guess. I've used Critter Sitter in 2014-2015, when I lived in Vegas. I've lived in 3 cities since leaving Vegas and I haven't found anyone who comes close to Patti.
We have 2 cats one is extremely shy and scared all the time and the other is needy. I had interviewed 4 other pet sitters before Patti and my cats just gravitated to Patti. She is very trustworthy, kind, and professional. She sends updates and photos, replies quickly to inquiries, is very reassuring and loves what she does and is great at it.
Ever sitter/boarding place before and since have left my cats a little stressed out and we were very lucky to find Patti.
