Graemer, how are you doing today? I hope no more limping so your mommy won't be worried anymore! Casper has had limping problems few times too, he made their scratching pole toy fall and hurt himself there, and kept limping for a while, but it went off then. Of course I was about to call the vet, but my husband said let's wait and see, it should go away since he still can walk and wasn't laying down all the time. Few hours later, he was fine again, I guess the most came from the scary fall, not the fact that he got hurt....
