Oh Heather poor Max - hope he's feeling a little better. Elizabeth's dog Tricky (dog) has this problem too - totally allergic to fleas she comes up in great big sore red weals. So with monthly treatments - Advantage - and keeping bedding sprayed with flea treatment together with the odd bath - seemd to do the trick. Course it's easier to bathe a dog than a cat!!
Anyway fingers crossed for Max.
