@Samuel836 It's either on for the listing's whole calendar or off. So your options would be:
1) Just turn IB off completely until you're back from your trips
2) Create a separate listing for the same property that is non-IB, with availability only for that time window and text that explicitly describes the different circumstances involved with the stay, or
3) For your cats' sake just block those days off altogether.
3 is far and away the best choice, in my opinion. I don't recommend leaving your pet in the care of a random tourist who's renting your room, and as a new host it's so early in your venture to risk so much going wrong. So instead of trying to cram in more Airbnb bookings, why not look to your social connections for someone you trust to do some catsitting in exchange for a free stay in Edinburgh?
