Also just a warning for people with long haired males - I used to use
Megazorb for Winston, but he started itching which lead to his fur thinning. I went to the vets which said he has Cushings but it's been around 4-5 months now and his fur is better ever since I changed his bedding. I figure it's the dust which gets trapped inside his fur due to it being long, which causes him to scratch a lot, which causes thinning. I changed his bedding to ripped up toilet roll and he's much better ever since
