We are thinking about getting two cats, but suddenly I am phobic about the flea possibility. I am mildly allergic to their bites and react much more strongly (local persistent swelling) to cat flea bites than most people. In my limited experience UK cats rarely have fleas, but now I've found loads of MN threads describing chronic flea problems & the detailed measures people have to undertake to prevent & treat.
Is it likely our cats (would go out doors, rural East Anglia) would get fleas regularly?
