Saw a commerical on TV that recomends year round flea protection and meds for cold weather joints. I thought that you only had to give Frontline, ect. During early spring-thru fall. I uderstand that fleas have 6 month long life cycles but the meds kill everything. Can fleas come into a house with untreated cats during winter in northern minnesoda?http://www.thecatsite.com/forums/ima...s/confused.gif Do any of you buy joint meds during winter? I find actually needing them in a centrally heated house is a screw over for $ (just my opinion) Am going to buy from pet meds this spring howeverhttp://www.thecatsite.com/forums/images/smilies/wink.gif
