It just shows how much we all learn on here. I would never take the advice now but 3 years ago (when she was 4), Kylie came in limping so badly that I thought she had broken her leg. I called the vet straight away and the receptionist asked if she was eating. Strangely she was at her food bowl at that minute, even though she was obviously in pain. She said "As long as she's eating, she can't be to badly injured. Don't bring her in but if she's still like it tomorrow, then we will make an appointment for you". As it turned out, she was a lot better the next day andthat was that. Although there are bad things it could be, I wouldn't panic and expect the worse, although I would get it checked ASAP.
