Nezumi - means rat in japanese, recently I have visited a couple japanese baby name sites.
I got Mika, which means having to do with the night sky, stars, and I think a name for the milky way.. I picked that cuz my Mika is black with white down her chest and belly.
And I recently named Kane, which means a few things like Tribute, warrior, and beautiful. I picked that because when I saw Kane all I could think was "Shes beautiful" and she also reminded me of my first rat Raziel so tribute kinda fits, and I want her to be strong like a warrior.
Maya, Spike, Naru, Yuki, and Maxine were named after anime characters that their personalities reminded me of.
Ruben was cuz he had ruby eyes
and Raziel was after that game Soul Reaver.. yea that long ago.. cuz I just fell in love with that name and he had white on the neck of his hood like the character's cape.
My advice would be to think of something you really like, like candy or a game or something. My friend has cats named Onyxia and Rexxar, even.
I really wanted Ice cream for like a week when I won a goldfish at the fair.. so I now have an orange and white fish named Sherbert lol.
