Hi there, I have a boar piggie who is around 6 months old and noticed a sticky spot just above his bum. I initially thought it was strawberry he had sat in but after a close look thought it was way too sticky for that. After some research it seems it’s his grease gland. I have never heard of grease glands before but I do think it is that, but I am also worried that it maybe something bad. Any advice would be great, I tend to overthink everything haha
