Charlie has been taking care of our cat (and used to care for our late, old beagle), and done it with grace and consistency. This is important because both of these girls were diabetic. Being on time is critical, and being reliable a must. I leave on a trip knowing my girl is safe. Never even have to think about it, because I know Charlie's on it. Even when I goofed up the key to the entrance, he was on it. Greatly appreciated!
