I have slate on my enclosure and my tortoise often rubs his nails and beak as he eats and walks over it. Is there like a special type of nail clippers I should use? I've never clipped my tortoises claws before so not sure how far I should trim.
I've never had to in almost 25 years.
I have cement pavers that my tortoises walk over. Placed at regular intervals in my enclosure.
If slate is not rough enough, you could try overturned ceramic tiles.
