Is this a rat tail cactus?

I was wondering if someone could tell me if this is a rat tail cactus. I've been looking at pictures and I think it looks the same but some seem to have yellow spines. Thanks.

Here's a close-up picture.

Thanks, I was hoping that's what it is and just wanted another opinion.

Beautiful Plant ... the flowers on the photo's in Plant Files resemble flowers of the Orchid Cactus! Very Pretty!
