Why did my guy friend send me a bunch of cats videos and pics?

I'm a big cat lover and he knows it. He never really talked to me, sometimes he puts his hand on my head, grabs my hand before he leaves. And suddenly that night he sent me cat videos, it was weird because he hadn't texted me before. And what I know is he is not really care about cat (not hate). But he loves to talk about it with me. What did he want?
