Re: Carefresh & Mites
The afflicted rat was the only one on Carefresh.
The second round I searched for why this was happening. I found many people on the rat forums had the same problem with Carefresh. Herisson and the hairless rat only used SoftSorbent until they were all switched to liners and never any problems.
It's a rat specific mite that the vet said most likely would not affect Herisson or the hairless rat because it lives on the rat hairs. The vet said they can be carriers even if they have no symptoms. This is why they were all treated, to break the cycle. Each round of this runs about $100 and agony for the affected rat.
You can google it for yourself and see.
