I've just found something out and it worries me. I used a dewormer on my kittens a while ago and it gave Archie a very red raw spot on the back of his neck, which then scabbed over and did not look comfortable. Tilly was fine. It's just that I was pet food shopping recently and I saw that on the dewormer packaging it says its also used under a different name as a perscription! Would it be exactly the same? I'd hate to think that vets were telling people to use something that hurt my baby.
