Hi,
I have two indoor cats, they don't go out except on the balcony. After
a recent move, we noticed some fleas where the cats were hanging out
(mainly our bed and now on a blanket covering an armchair). The thing
is we only found 2-3 fleas at a time (5-6 the first time over two
days). We cleaned everything, treated the cats even but some blankets
in the freezer because on web site said it's the only way to kill flea
eggs. The fleas disappear for a while then come back, again only 2 or 3
in one spot. We checked the cats the last time and they didn't seem to
have anything. It is really strange. Anyone have any idea?

Thanks!
