We keep getting the odd one jump onto Simba. The other's are free of them, but Leo is allergic to the buggers. We've even used the 'vet recommended' spray.
I've not had an issue with fleas since 2009 - when I came back with fleas from a show. Both me and my cat were hopping with the bloody things...
Pearl had been penned between two cats belonging to an exhibitor who was well known to show management as having cats with passenger issues, and of course, the little bar stewards migrated onto my cat. And then migrated onto me during the two and a half hour drive home...
Fortunately we don't see the woman any more. Her entries now get returned by the show manager saying sorry, the hall is full. She used to have a habit of turning up just as vetting in was closing, which was how she escaped the more stringent checks.
On another note, a box of the girls' usual treatment and four wormer tablets turned up in the post today. Tomorrow I shall be chucking a Drontal down each cat.
