I would also recommend a pet sitter, verse bording. That way your cat can still stay in the comfort of their own home.

Here is another large listing for the USA.

I used to work for 3 different pet sitting companies, they are all different. Make sure you meet the person who is to be your pet sitter first, go over EVERYTHING with them. I personally like a person who will let me call them and check in, and who will leave a note before they leave, and I return so I can know everything that went on while I was away.

You can get someone to come once a day, or 2 times a day, normally for about 20-30 minutes each time.
Or you can get someone to come around 6pm at night and stay the night in your home with your animal. Idealy they are suppose to spend all their time at your place with your animal, unless they have to go out for un emergency.
Rates will varie, but can be about $10-15 per 20/30 minute visit. Or $50-80 per stay over (staying at night.)
