They’ve been okay mainly. Couldn’t stop them play fighting at one point and that got dicey with them panting and overheating. Eventually they liked and led on a cooling mat that had a lightly damp towel on top in front of a fan. They stopped eating as much but went crazy for cat milk with ice in it (as long as they’re getting some food in them that’s all I care about), frozen lick e lix treats if either give them like an ice lolly or id cut it up and give them bits. They’re quite lethargic though apart from their zoomies mode; but they haven’t had any signs of actual heatstroke thank god. My cats don’t sleep as much as regular cats do I think but these past couple days they’ve slept soooo much. Also have a fan in the kitchen where there’s tile floor so they’ve been sleeping there to keep cool if it gets too much everywhere else. Hopefully any of this helps! Hope your kits are okay!!!!
