Actually, Frodo is a good name.
I know I'm late with the comments. lol.
My cat, Frodo is still alive. And basically she (yes, its a SHE) has lived the longest out of all my Lord of teh Rings-named cats.
I used to have Legolas, (new one and alive, Siamese cat)
Boromir (Still alive),
Faramir,
Aragorn,
Bilbo,
Arwen,
Galadriel,
Merry,
Pippin,
Sam (Still alive) and
Eowyn,
Gandalf.

Aragorn died a long time ago but suffered the most painful deaths. I cried when he died. (My cat that is!)

Good luck with the new Betta. :)
