What is that? Do you see it? Loki has these four vertical marks on his side.
What is that?
They are crate marks! He slept in his crate and must have leaned up against the side of his crate. (We didn't even close the crate; he just voluntarily chooses to sleep in there.)
But why these marks?
Ah, because we gave him a bath last night and he must have slept against the side of the crate while still wet.
