But the legs weren't the biggest worry. The chest problem was. We would have like to have x-rayed to see exactly what was going on, but we'd missed an opportunity when he'd been neutered and we didn't want to risk putting him under anaesthetic again when he seemed perfectly healthy. You'd have thought having your heart open to the world would be terribly dangerous for a wee, active kitten - so we came to the conclusion that he must be less vulnerable than you'd think having joined in with the rough play of his siblings with no apparent harm done. And, as he grew, he built up muscle mass around the gap and seems to be getting on fine. I'm terribly careful picking him up just the same.
Without x-ray it's difficult to say what his problem is exactly. I've found information on pectus excavatum and FCKS that seems the most likely. Surgery is recommended in severe cases but, as Curly's seemed mild, Fachtna recommended to leave well alone and keep an eye.
So, I spent several months dithering about whether to advertise him for adoption or not. And, in the process, I fell in love with him. And so did Moe, my wee wobbler, just a few months older than Curly.
