A few weeks ago I looked after a friend's cat for 2 weeks. She only stayed inside during that time although she is normally an outdoor cat. About 2 weeks later...we seem to have a flea infestation. I did a bit of spraying with flea spray but it hasn't helped at all and things seem to be getting worse. I'm sitting at the PC here, felt something moving on my head, shook out my hair and about three fell out 
The awful thing is that we had a nasty episode in May with fleas that were living in the garden, left behind by foxes, they were getting brought into the house on our clothes and I was getting bitten alive. It took ages to work out what was happening, I thought we had bedbugs! Those fleas were bigger and nastier...they left massive bites like mosquito bites and at one point I had over 200 on me. Anyway...we dealt with that but that was outside...this is different as the infestation is actually in my house.
I'd be grateful for any suggestions for what to do about this...me and my three teens are not at all impressed.
if this isn't the right place for this thread I'll ask for it to be moved...it's just that we don't have a pet as such I wasn't quite sure where to put it.
