I mean heat is painful for all animals and that’s not really the reason why they should spay their cat, but yes. Please spay your cat as soon as their heat is over (I’m giving op the benefit of the doubt of this is their cat’s first heat and they’re following recent vet recommendations until waiting after at least the first cycle to spay the animal)
Ofc! My best advice is towels/wash cloths over your cat’s favorite lounging spots to deal with any spotting on furniture and whatnot, and a comfy spot in a warm sunny window may help their comfort, but otherwise animals are pretty good at cleaning up after themselves so let her naturally handle it as much as safely possible
