I'm cat-sitting now, I come in late afternoons and stay for about two hours. The people I cat-sit for have a "professional" cat-sitter as well, who come in every morning to give the cat wet food, and I think, empty the litter box. I'm not impressed though, as when I came the first day, the sitter had emptied a can of food in to a bowl, without cutting the food up. I e-mailed the people about it and they contacted the company. I also have a feeling that this cat-sitter is there for just a few minutes only. I'm certainly not going to recommend them to anybody! They charge about $17 pr day for this.
