Totally agree Stubby , fool & there money are easily parted in my opinion , its why places like pets at home sell all this stuff, if a ferrets kept clean & its bedding changed regular they dont need bathing in ferret shampoo .
As for that beapher stuff its mainly ivormec & a carrier i suspect , but one question thats been asked off Beapher & they didnt have the courtesy to reply , does ivormec actually kill fleas ?,
I dont think otc stuff is any good anyway, i wouldnt use anything other than a veterinary preperation for fleas , its false ecconomy in the long run
