Ha I can sympathise,when we got Jess and Dylan when they were 8 weeks old,we rescued them from a stinking filthy pit of a house,they were riddled with fleas and ear mites,we immediately got spot on for them and we treated all the other cats too,then we hoovered twice a day for a week and then flea bombed the house,which was quite hard to do with 10 cats but we put them in our room locked them in,flea bombed downstaira and then when safe moved the cats downstairs and then flea bombed upstairs,then we hoovered twice a day again for another couple of weeks and then once a month passed we flea treated them all again,and now finally no fleas
The little hitch hikers have hitched their last ride to the flea garden in the sky
Took a lot of effort but we needed to with 10 cats could imagine if they got infested
Everytime you see flea kill him
One less flea to breed oh and lots of hoovering
Then watch the critters drop off dead after the spot on
