Some of you might remember me mentioning worming being done every month - I thought of asking the vet about it tonight, and apparently, they (not sure who she meant by they actually, but some people!!) are wondering if there is a link between an eye prob and a certain type of roundworm - unconfirmed, and they dont know which roundworm, but it only affects young children and immuno-compressed, so that is why they are now suggesting monthly worming, and my vets are doing it really to cover their back. Do wonder why no one else is being told it though!!
