This is not meant to be discriminatory. Every cat is beautiful, but which which color do you personally prefer?
I personally like orange cats or orange/white mix, but I couldn’t find one at the rescue that was set up at PetSmart so I was depressed, lonely and I was desparate for the love of cats got so I just adopted a tabby brown cat.
My least preferred colors are pure white or pure black cats, but I somehow still like a mix white/black cat. I mean, if one showed up to my door and was friendly and had a great personality, I’d take him/her in, but I probably wouldn’t be looking for those color of cats if I were looking to adopt a cat in a shelter/rescue.
Are you being a bad person by picking cats based on their color? To be honest, if there was an orange cat at the PetSmart I’d likely not have chosen my tabby brown. I kinda feel horrible for thinking this way, but I mean, it’s just like this weird feeling, this attachment to specific color cats. I just loved orange cats so much. But once I gotten to know my tabby brown, I now prefer tabby browns as much as orange cats.
Again, every cat is beautiful, but I just have weird preferences for some over others for some odd reason.
Edit: To be clear, I was looking for ANY cats, but I wanted an orange one if possible, but if not, I would’ve taken ANY cat. I didn’t care that much, I just wanted some cuddles with a warm little fellow living being.
There’s nothing wrong with having a preference. At the end of the day, when you adopt a pet - you are saving their life and dramatically changing yours. How you come to that choice is deeply personal. It doesn’t matter if it’s superficial or whatever, least of all to the cat. As long as you give them love, warmth, food and shelter.
 I don’t really have a preference on breed, I just care of they’re sociable and friendly. I do have a preference for girl cats. My dearly departed cat was a girl, and my wife’s cat (very much alive) is a dude. Love him, but it’s not the same.
