Hello! I am wanting to give my 10 week old rabbits a fleece blanket in their cage but before I do that, I am unsure about what the safest way to wash them would be. Ive read mixed things about using normal laundry detergent, unscented detergent, and just plain water. What is the best way to wash a bunny fleece? Im sorry if this question has been asked before, but I dont want to do something that could possibly harm my babies. Thanks!
