I bought some straw for a baby rabbit. I was keeping her in the house until her injections kicked in and was using puppy pads under her sawdust. Put some straw in on the night. Within a day the whole cage was crawling with these. Had to take the rabbit to the vet and get her unstraw mited. We had to throw away her toys that could have got mited and had to pay for the carpets to be cleaned. The vet put the bugs under the microscope and they were straw mites. Must have cost me £100 to pay for vet, treatment, new toys and carpet. And did home bargains pay me back? Did they heck. They offered me an instore credit of £30. So that would actually cost them £10 after profit maybe!
