OBT Burrow

[Terry Henshaw]

My obt sling has closed up the entrance to its burrow with substrate. What would be the reason for this?

[Peter Lacey]

They are burrowers, they'll web it up if they're not hungry or if it going into a moult.

[Peter Roach]

Very normal, just leave it alone until it comes out which may be a few days or weeks
