Who says 3's a Crowd?

Here is Little Lucy amongst the big boys. (keep in mind she has doubled in size in past 3 weeks).
Diablo, the Siamese, has warmed up to her and they chase each other throughout the house. But Shadow, the fat cat, has not. (And HE is the one who needs to be running around) He still glares at me each time Lucy is in his vicinity. Its comical. And little Lucy will try to play with him but he isn't having nothing to do with that....yet.
