Yeah, I also thought since she has a red tail, it would be an ok color for her. But, we got to the vet and Merlin didn't want to come out of the carrier and the vet remarked, "Your new Grey Mom doesn't know you don't like red." And she told me Greys hate red. I also have a ton of red shirts, lol!
Well, we found out Merlin is nearly blind, so I doubt she even knew it was red, but just decided to tell the rest of you in case, like me, you weren't aware of that.
I was told Pete, the zon, doesn't like red, but so far I haven't seen any evidence of that. I did ask Merlin's former owners if there were any colors she didn't like, and they didn't think so.
But, it turned out Merlin has very severe cataracts, which none of us knew, I'm pretty sure. She probably only sees shadows, and probably only with one eye.
She did come out of the carrier when I asked her to. So she does at least know I'm her new mom. She must know my voice and probably my smell. The vet showed me how she is always "tasting the air" by sticking out her tongue to learn who/what is around her.
I started last night talking every time I moved around so she would know where I was. And no more hiding in the corner when frightened, so I think that helps her.
She hasn't had any more night frights either since I put on that little lamp for her. We will keep using that.
