If you have someone trustworthy to come in twice a day, that's a good option. Or you could take them to your mother's if she has no other animals. We have boarded our cats. There is a place about 2 miles away from us with really first class accommodations. However, some cats really hate anything new while others don't seem to mind. Kitties do hate change. Just a funny story when we had two cats we boarded them for two weeks. When we got back we heard about what a sweetie the tabby was and what a holy terror the tuxedo was. When I went to their kennel, the tabby was all happy to see me but the tuxedo took one look at me, turned his back and walked away. We had to apologize profusely - poor guy felt so betrayed.
