Thanks everyone.

Ive isolated him because hes picking on my older rat and is due to be castrated so I will get the vet to answer about if it was him or not.

I do wash my hands after I touch him too, Im trying to avoid touching them too much atm anyway, I free range them so they can explore on their own.

It is soo itchy. I've noticed that its gone down slightly from yesterday. Sadly I've been taking photos to see if it does go down.

just read the leaflet inside the ointment box and it says I can apply the cream 4 times and on the box it says 3. I think I will apply 4 tonight I feel like my skin in bubbling from underneath

Sorry to moan on, I cant talk to many other people without being told I'm diseased.. Mature friends!
