I never use inscence, candles or any kind of spray or freshener around my rats as I know they have respitory problems and can even die from the sprays, but seeing as ferrets are more like cats and dogs these things are ok right? Cos we like to have inscence etc in the room but dunno if it would be too smokey. We would like to get a freshner type thing (eother liquid or jelly) to go on the wall.
The ferrets still snore and they sneeze now and then , but only when washing. They have started to leave a few hairs on their blanket since the colder weather so I think it may just be that. thanks.

Your local vet should do a product called odour eleminator, its pet safe from memory and has an enzyme that digests the smell or something like that. Give em a phone call and they should put you right.
