Dendrobium or a Cattleya?

[Sommeil]

Hello everyone!
I've been growing orchids for a year now, but I still consider myself a newbie. I just got my first phal to start spiking and that alone is a huge accomplishment! Aside from that, I am having some trouble identifying an orchid I bought last summer. The label only said it was a dendrobium orchid... but under furthur inspection, I'm starting to think that it is actually a cattleya. Unfortunately, I don't have a photo of the flower, but I can show you it's leaves. Please help me identify! Thanks in advance!
