I know I know!!!!! I just bought the *cutest* collar for Marta there. It's Aspen Pet, it's pink w/ sparkles! It looks so cute on her, and it would look fantastic on Lily. I know they have small ones too! .

Edit: I just checked petsmart's webpage and they don't have it on there, but still it may be at your store, it's like the regular pink ones (a bit darker though) but with pink sparkles.
