I just sit with my nose in their fur.....the boys smell so scrummy. they are very big boys. they weigh over 600g .....I am addicted to their gorgeous musky smell.....the girls just don't smell as comforting. the boys smell like the fave teddy you had as a kid.....I adore rats. I will actually cry when they shuffle off this mortal coil.... ...they have such huge personalities, (and sucha fabulous smell!) I have 9 of them. I really do love them. and their furry smell. I w8dh I could take em to work....I find their smell calming...yummy boys.
