Agree, may struggle to wash it frequently. I find that towels go pretty whiffy but if it works for you then it works. Under my fleece I use human-incontinence pads for, for example, children who wet the bed. I’ve had mine for about 7 years now and haven’t had to replace them yet and they are washed weekly. I was mine with white vinegar and a dash of hibiscrub. I think they were about £10-£15 for a two-pack and a two pack fits a 2x4 c&c cage.
