We have "vetericyn plus" here in the US. Have you heard of it there? It's my go-to resource for wounds. We get it at the tractor supply store because it's cheaper. Also you can get a large bottle sold for horses, at the same price as the smaller ones, and it's exactly the same ingredients.
my vet uses it to keep all wounds clean, on dogs, cats my horses, reptiles, sugar gliders...
I think you're doing a great job in such a short time with Abaddon, she is stunning

Hopefully she will be feeling better soon. I'm sure she feels better already with that thick shed!
