His name has to sound different than Heidie so the cats don't get confused when you call them. Human sounds are subtle, and you want a name completely different for him.

So, how about:

Shoe
Homer
Flash

If these or none of the others do it for you, don't worry, his name will come to you eventually.

i named my cats names like boomer and ziggy. i also like names like Nyda, you can look at these names too.
Charlie
mason
dicen
barly
sherlock
milo
mossy
uno
cleo
if you need any more help just post a reply. i hope that you have fun with your new kitty. hope you like the names!

made them up

Socks! just kidding haha. I like Kreider, or Moon, or something like that! haha :) You could even go to a baby names site, sometimes you can find cute things there, just google baby names! Whatever you name him it will probably be cute :D

As much as I dislike cats, my roommates have some good names for their cats. Like: cat, other cat, fat-**** cat and side-ways cat (he walks funny).

These are their names.

heidie huh how about ho like heidie ho neighbor

I would have named him Moonlight or Midnight or something to deal with nightime.
Or go to www.2000catnames.com

What's its gender? I would recommend Sammy for a female, and Toby/Tommy/Tom for a male.

Mitten if he has a white front paw.

Giggles

name him spencer....like heidi and spencer from the hills.
