I have spent a lot of time with cats since I was 10. I love cats and the characters that each has. Cats are not as friendly as dogs and they need space and time to trust someone new so I don’t touch and pet cats until they allow me to. I make efforts to build up the trust between us also to make them feel relaxed and comfortable. I have 2 cats in my house. They are indoor cat. We brought them from Japan and I am sure that they would feel fear and so much stress while being taken to different place because cats normally don’t want go out and they want to stay where they feel safe to be. So if your cats stay in my house I will let them stay in separated room from our cats so that they won’t feel nervous. when I visit your house to take care of your cats I will take time for them to cultivate a good relationship:) so don’t worry.
