Santa's molting. They usually shed theirs on February.

When they're shed, what I do, is just brush their fur, clean their cage and let them go out and get some fresh air. I'm sure they must get some stress. 

I like this photo well because it's really hard to take Mango and Santa's pic.

Also like Santa's face. :)

Ferret's always sleep together. 

Mango, she always looks me like that eyes.

Last, her favorite time, when they eat some treats.
