"Dx". Hmmmm, you must be in healthcare. Only a healthcare-type person would say "dx" instead of "diagnose"! I sometimes find my work "shorthand" creeping into my other life and can't figure out why people can't understand my notes - leaving a note for my son saying "remember to do your hx homework" for some reason goes ignored!

Anyway, I don't think the tux pattern breeds true. My two tuxes have a blue cameo tabby mom, and even though I don't know who their dad is, I never saw a black and white, or even and -and white, in the neighborhood before she came up to our door, preggers and homeless. Their sister is a brown tabby, of which there were LOTS roaming around.

Keep us posted on your little Chilli!
