I've got 2 cats and I've already been doing dog sitter for friends and my cats aren't scared of dogs. I'm took the dog outside 3, 4 times a day depending on the information I had. I usually play with them outside and inside. I feed them as well, just need to inform me how many times per day you feed them. I let them do there life in the flat they can sleep anywhere they want. I love animals and I'll treat your dog like it's mine. I can also send you picture and information during the day about your animals. So you will feel confident and will know what your animals is doing. I'll give my best to make them feel at a second home. And will dog sit them as many time as you need and want
