Comrade

Comrade is a dog, or so that's what he thinks. He's really a cat, but Comrade thinks he's a dog and so he acts like a dog. That really frustrates his best bud Spot, who ever tirelessly tries to convince Comrade he's a cat, but Spot's never successful. Comrade might not be the brightest cat around, but he is the most "loyal" cat around. Tomorrow we will meet Spot, can you guess what animal he is?
