Noble cats

Kind of advertising to give away my 4 new-born kittens, to put in my school [That's why it's written in Italian]...

It says:
"I GIVE AWAY BABY CATS
from half June.
For information, ask Paolo Fausone 4th E class."

[Sorry for the bad translation ]

I've called them as the 4 first noble gases: Helium, Neon, Argon and Krypton.
