Firstly I don't think my nerves can take much more but last week we were playing with the laser toy and Milo was running around for 10-15 minutes, all of a sudden he sat on the floor stretched out and was gasping/rasping for breath, it was really frighting, his heart was racing, then after about a minute he got up and carried on as if nothing had happened!
This has only happened once, but now when he plays with it he isn't quite a mad running around, I've spoken to our vet at work and said get it checked out as it shouldn't happen in a 6 month old kitten!
Now I'm thinking all sorts and getting neurotic!
