80 or above is too hot for a rabbit. You would need to cool their habitat in some way and ice packs/bottles won’t be enough.
If you don’t have indoor space and already have lots of pets it may be best to wait until you’re older and have room/time to get a rabbit. Another thing to consider as you are younger is who will pay for vet care? Rabbit vet bills can get into the $100’s easily have you discussed with with your parents? Are they willing to pay for this? Time is another commitment. How much time are you going to be spending with them. One issue that comes up with outdoor rabbits is you don’t see them as much. Just having rabbits to have them is not fair to them. Unless you’re planning on spending most of your day in the playhouse with them?
I would definitely discuss the cost of care with our parents and re-evaluate whether or not a rabbit is a good pet for you right now.
