I've found Frontline stopped working for me AND it made all of the cats foam at the mouth!!!!!!!eek:, so I switched to Advantage (not sure if that's available in the UK. I've also since read some studies indicating that the main ingredient in Frontline, fipronil, is a carcinogen, for what it's worth.

Oh my goodness, I've had loads of replies and I didn't realise!!! I usually get email notifications when I get a reply, but I haven't!

Anyway, thank you all very much. I spoke to my vet almost in tears coz I really hate fleas or anything like that! They said it was safe and a good idea to Frontline both my 2 cats and my dog with the spot on every month. Also I went and picked up some Staykill household flea spray and sprayed my entire house. I am very pleased to say that I have not seen one flea on any of my animals, so I'm over the moon about that! From now on, I will continue to do them all monthly and do my house once a year. My vet said they don't sell advocate, they recommend frontline spot on still as the best flea reatment. They said they could order it in for me though if I wanted it! As I have seen no further fleas, I'll stick to what I'm doing now, but if I see any fleas again, I will ask for advocate!
