It usually takes me a good week or so before I name my cats. That way you have time to get to know some of their personality traits and something always comes to mind. Give it a few more days and you'll come up with something.

My newest kitten I adopted from the vets and they named him Slick because he had a spot of oil on his forehead when found. I started calling him a pip squeak because he was so much smaller than my others cats and he got renamed to Pippin, Pip for short, and it suits him well.

Never rush naming a cat
