Same here - one of our cats limped home like it had just been hit by a car, we phoned the vets in a panic and were rushed through a busy waiting room like a scene from casualty
Cat emerged from the carry case like it was wondering what all the fuss was about - no sign of a feckin limp
I don't remember if we were charged for that visit but I'm sure we would with these new c'nto owners.
As an aside - our dog is insured but our cats aren't, not entirely sure why we did/didn't!
