Hi, I have several questions so please bear with me. I've kept mouse for the last year and adore these little creatures (they are actually my daughters but she is now at Uni so I became a mouse mum). I have 3 mouse together in a cage (and 3 babies kept separately). My oldest mouse Ellie, now 14 months, started scratching and very quickly lost fur and part of her ear. She has been to the vets and been treated for mites (first treatment given by the vet) and had antibiotics. I had separated her from her friends whilst she had her antibiotics and I also mite treated her friends too. I've stripped down the cages and disinfected everything, put the toys and the bedding in the freezer for 24 hours once cleaned. They went straight into disinfected cages once treated. I have two sets of everything so the cages, toys and snuggle sacks get thoroughly cleaned every week normally anyway. I only use paper bedding but clearly this is where the mites have come from. The other two mice in the cage (8 month old sisters) have scratched a bit but not much but it seems to have really effected little Ellie. Now she has finished her antibiotics I have put her back with her friends as she was clearly getting lonely. They are all due for a second mite treatment next week. They hated it but a bit of banana afterwards seemed to take their mind off it. I've been told to bring her back to the vet after her second treatment if she is still scratching, which I will do. Questions: Little Ellie is still scratching so much and it's heartbreaking to see her. Is there anything else I can do? Is there something that will ease this for her? I know I can spray their bedding with Ivermectin, which I have bought and that it should be a 1:5 solution but when do I do this, how often? Just when they have the mites or prophylactically? I don't want to overdose them. Can anyone recommend a good quality paper bedding easily available in the UK? I want to avoid this again if at all possible, it's the first time in over a year any of my girls have had a problem. I feel absolutely terrible that my girls have had to go through this so any advice would be gratefully received.
