Mardi Gras Question - ANSWERED (THANK YOU)

[Maxwell Grantly]

I wonder if any of the more experienced members can help me.

I was thrilled to get a special kitten (a Mardi Gras Fat Cat girl) and so I gave it away as a present to my younger brother.

However, after passing the cat to him I wondered if I had made a stupid mistake. Does his receipt of my present exclude his cats from birthing his own special cat over the next few days? I would hate it if my gift ruined his own private chance of getting a special kitten.
