After having had kitties for many years, I would highly recommend finding someone who is willing to come to your home and attend to your cats's needs.

Only once, in an emergency, did I board the two cats that I had at the time. They were so stressed when I returned home and one had rubbed his nose raw on the cage. It took me weeks to get them calmed down.

I swore I would never do that again. They are better off in their familiar surroundings, even though you are absent.

Secretly, I think we always miss them a lot more than they miss us. However, my Calico who would be overjoyed when I came home, would soon remember that she was mad at me and then would have nothing to do with me for over a week. Talk about punishment!
