Moss and Munk..

So I've been having a hard time figuring out why our cat Munk(half of the Chip Munk wondercat duo) has developed two dark marks on both sides of his nose. I tried to clean him up to no avail. Tonight I caught him rubbing up against the wood in one of our moss planters. He could take it out to play with it. Instead I see him rubbing his face on one corner then the other, of the stick in Paige's moss. I guess the girls cats like moss too!
Here's some moss inspiration I found on etsy today.

Teresa's Plants great stuff....I mean moss.
