I have never wormed Trigger and Tiffany, as they never leave the enclosed back garden, and the odd mouse or bird caught by madam has always been rescued alive, or if killed, always intact
but Tosker, who can get in and out of the enclosure, has twice brought in a dead bird, which I have found half eaten, presumably by him - I doubt either of the other two would touch his kills
I have been putting Advocate on him a couple of times a year, but does he now need more regualar worming? and should I be treating him for tapeworm, which is not killed by Advocate?
