When cat went I put her food in the food bank (I hope they didn't think I was being funny; it was for any struggling family who might have a cat), then gave her litter and the indorex to a girl at the local shop who I have 'cat chat' with, she has several cats.
I've had the occasional flea since my little one went but put on a cashmere jumper the other day which I hadn't worn since and was besieged by them, albeit they were fairly feeble.
I need more indorex, don't I? Endless cleaning and vacuuming? I can't ask the girl for mine back!
You have to admire the fleas in a way, they're certainly persistent (and love wool and cashmere)
