I have 3 gorgeous ferrets who live in a spacious converted avairy but I can't get them to litter train. They don't all use the same corner and will not use a litter box - I have tried putting their mess in litter box with fresh litter but they just tip the box up to empty it & then sleep in it.

It's getting really smelly & looks horrible when people come to look & you've got 2 messy corners. Help & advice needed please.

Also, last 2 days their mess has been quite loose - not as firm as it should but not water - they are fed chudleys ferret dried food - have they picked up a bug??

Any help & info gratefully received - Ange
