Your babies are all absolutely adorable

!
I'm assuming, since you stated that Jack is on a diet, that Lily is the brown tabby and Jack is the red and white tabby. Am I right? Either way, they're both incredibly sweet and look as though they get on well with one another.
And, Boo -- what a cutie patootie she is! She reminds me a lot of my little guy, Finnegan. Here's a picture of him (he's just around 8 months old as well):
Finnegan is a DLH, of course, but he has similar markings to your little girl, Boo and they have the same eye color. Boo is adorable, though, and looks as though she is posing for the camera -- what an excellent little model she is!
Thanks for sharing pictures of your babies. They made me smile this Sunday afternoon!
