Hi I'm my sixties now and had ferret nearly all my life, when I was a youngster we used feed them on bead and milk an egg now and then rabbits livers when we got them. I feel so guilty about that, we were ignorant we didn't know any better it was what are fathers taught us. We didn't even have freezers. Now with the internet we can find out all sorts at the touch of a button. Ferrets lasted 3 to 5 years now may 8 to 10 didn't know about jill jabs as well. I spoil my ferrets now (I think) vitamin malt lick, handful of dried food Alpha or James Wellbeloved through the day and in the evening ha
