when you have kits, especally a large litter, feeding twice a day, kits and mother cost money, and as your feeding alot, the cage needs changing either everyday or every other day, shavings ect also costs money, so after 8 weeks a tena a kit, polecat or albino, doesnt seem too much to ask , no profit is being made, just recooping the money spent, my 8 kits are 5 weeks today i think 6 or 7 has theyr eyes open, and all are feeding well, the polecat i bred from was a big hob, the mother is a small albino, so i have large polecat kits and small polecat kits, only 2 albino's,1 jill 1 hob
