Urgh YUK YUK YUK!!!! Thanks very much for all of that!! LOL :D
Believe me Margot, I am scratching as well!!!
The frontline has seemed to work - on the cat! As I said I haven't seen any fleas in the house, I have been on all fours with nose in the carpet and bum stuck up in the air (you get the picture!!!) with my glasses on, and a magnifiing glass, and not seen any even under the sofas, but Thomas is still getting new bites which makes me think they are lurking somewhere (and probably laughing at me for not spotting them!!!)
I think I will get hubbie to pop in the vet's on the way home and pick up some Acclaim, and a flea collar, and then when he gets home he can check the cat for any bites. Goldmali, if she does have bites on her, does that mean it is fleas, or mites? Do mites bite them? and do mites need a different treatment?
I have heard all sorts of horror stories about how difficult they are to get rid of out of the house, my sister had her house fumigated twice because of the fleas the previous owner left behind

I hope it doesn't come to that!
Off to have a good scratch now :D
