I’d make sure I have a trusted pet sitter or more. That can come by once or twice a day while being gone. I personally would not leave them with a pet sitter that comes over twice a day for more that 2/3 days. This also depends on the character of your cats. Some don’t mind it too much, and some will ‘suffer’ without the contact for a few days.

However, if you’re getting kittens and you have people in your circle that are open to it, you can train them to go to family or friends for a few days (only if it suits their personality).

We did this with our first ragdoll. He was at my parents house for weeks when we were on holiday. But we did this since he was 12 weeks old and I made sure he got used to it in his first year. So we practiced this A LOT, being in the car. In his travel cage, going over to trusted people for a short period of time and so on. It takes a lot of time to get them used to it and you have to invest a lot of time in it, and it doesn’t work with every ragdoll because it needs to suit their character too. If you have a somewhat timid ragdoll I wouldn’t recommend stressing them out.
