I have a question. Lincoln has been marking in the house for the past few days. Paisley hasn't been up to the house for a few days, so I don't know if he is doing it because he smells her scent.
He has marked in a few places. I hope this is just a stage. I don't think it's the cats.

Any thoughts.

This seemed to have stopped. Yippee.... Must have been a faze.
