Please could you advise - is it possible that mites stay in fleeces even after they've been washed? one of our guinea pig has bald patches on her belly and feet, now getting them in the middle of her rosettes. We've treated 3 times with Spot-on over the last 6-9 months as directed by the vet. For a while it started to get better and now it's got worse again. The vet suggested that we throw the hay that we were using out and get a new one the first time. I've stopped giving them a tray of hay to sit/eat in. But they've started to get worse again during Covid. This never seems to affect our other guinea pig. Please could you advise?
Thanks
