I agree.
I have successfully changed my cat Max’s name from Gadget to Max, but then what sort of name is Gadget?
I had a cat like the OP’s once and his name, he told me, was Boots.
Since he’s a Thanksgiving cat, how about Turk? (Turkeycat)
Or Tuck? (Tuxedocat)
How about Shad? (Shadowcat)
A neighbor of mine used to have a cat with a name that sounded like Siayti. I commented on the unusual name, and she laughed and said it was actually C-A-T spelled out, since they couldn’t think of a name for him, and it just kinda stuck.
Jester
Quinn, short for Harlequin.
How about beef boat.
Haw! That’s only in Yazoo City.
(Dear bleeding Jesus, you can take the girl out of the country, but…why do I even know that anymore??)
Holy cow, that cat looks just like my cat Domino. But Zorro’s good, too. Or Guido.
Bustopher.
Tennessee
As in Tennessee Tuxedo. Or Domino, like my last B&W kitty.
Brunhilde
I need closure. Paging appleciders! What did you name le chat?
Oswald Cobblepot! Oswald Cobblepot!
Fido or Bowser or Spike
My new favorite poster on the SDMB. 
Can’t open the photos from work. But being black and white, how does “Ascot” work?
Obama
He has become “Pirate”. A little uninventive, I think, but it’s my parents’ cat, not mine.
Since the decision has been made, I just came in to add…SQUEEEEEEEEE! Very handsome kitteh!
Tennessee
I always wanted to name a cat Mousey Tongue (ala Mao Tse-tung) because mao is also the Chinese word for cat.
