Cats heat bathing. But this isn’t our indoor cats, it’s one indoor and one outdoor one. The outdoor cat has been in half an hour. He usually stays that long, then I think he gets too hot and goes and yowls by the back door, ready to go back outside. In fact that’s exactly what he’s just done. Walked to the back door and mroowl, that’s it. So I let him back out. His introduction has to be on his terms. My boy indoor cat is sniffing where he was sitting. Luckily he’s on a flea treatment so everything should be fine and as mine are inoculated means they should be safe.
