A little odd since the cat is still alive - both
Noah's will meet each other. But, if the cat was deceased I wouldn't think it very odd.
Did
Peyton name the cat? If so, then it means she loves the name. Why not use it on a real baby now that she has the chance? I once named a chicken
Carmen. I'd still use that name on a child. I used it on the animal because I loved it.
