Marley has been pretty calm about Asher moving into his domain. Most of the time he doesn't pay much attention to him but every now and then he will get curious and sniff him. If Asher is in his bouncy seat on the floor and starts to cry Marley will get a little anxious and start to pace around him. I am not sure if he is upset by the noise or if he is worried about him. One day, I know they will be best friends. But for now they are just cordial roommates.
