I seem to remember Lonecat mentioning months ago that she'd heard something about a new product on the way which treats everything (including tapeworm)
My cats were in for vaccs last month & when I asked they said they'd just been told about it but hadn't got any yet. I've ring today & they've got some in \link{http://www.vetuk.co.uk/pet-meds-prescription-only-broadline-c-21_2047/broadline-spot-on-solution-for-large-cats-3-pack-p-20304& now I've got the name I've found it on vetuk too}
I suspect my vet will be charging a lot more - they haven't got a price yet! But I'll pay their price to get it off the shelf & sort out a prescription or a discount later. It's getting on for twice as much as Advocate on vetuk but I am hopeless at giving tablets so it's worth it not to have to try!
