i rang the vet and we are trying their worming tablets, its definatley not fleas i have checked throroughly as well as having flead her JIC.
she is a great rat catcher so i feel that is where they keep coming from. she is an outside cat who sleeps inside and mostly on DD's bed (everything is washed and we have been wormed too)
i did see a worm the otherday when she had been sitting on the bonnet of my car and cleaning her self(she left it on the bonnet for me.. blerg)
