Franta sounds like my cat Daisy Doo Doo, she is the most mild mannered cat in the world, would never hurt anyone, but go near her with Frontline, Drontal or anything remotely medical and she will have your hand off, Daisy is always the one we spend literally hours chasing round the kitchen to get anywhere near her to treat her. I do feel for you Gill becuase it normally takes two of us to even put frontline on her, I cant imagine having to give her an injection on my own, I am sure I would be shredded
Anyway, good luck for today, Franta be a good boy for Mummy
