Hank and his cat Cameo help teach us about animal behavior and how we can discover why animals do the things they do.

Vampire Bats regurgitating blood into the mouths of their comrades is somehow both heartwarming and terrifying. So thanks for that.
Green's cat, not to be confused with Pavlov's dog.
I have a Biology exam tomorrow and these videos are saving my life
"Horny Siberian Hamsters" should be a band name.
the SciShow team also produces the CrashCourse Biology videos... we're the same people!
Chicks dig nerds that can dance? Ladies...
A note on those South American vampire bats; they also exhibit tit-for-tat. In a somewhat cruel experiment, researched grabbed some bats leaving the nest and injected their sacs with air using a syringe and shoved them back in the nest. To their neighbors, these bats appeared to be engorged, having lots of blood to share, but this was only an illusion so the bat doesn't feed the other's babies. In return, the other mothers won't feed the babies of the bat perceived as not sharing with the others.
"The only two things that matter - eating and sex" is a rather sad statement...
What kind of cat is cameo? She is very fluffy :D
Through the whole video, I couldn't help thinking, "When does Cameo get a treat?"
Why is your neck red? Hmmm
You can explain things in 10 min better than my ethology professor in few hours. Thank you :)
your dog is so cute! I paid attention tho, i promise! :)
*I loved this episode!* Thanks Hank and the producers, there really isn't much to find about Ethology on the net. I have an important project in school next week and this really saved me a lot of time.
I've been in Hank's living room. It's like we're friends now.
I LOVE YOUR CAT!!! you're officially my favorite person!!!!! love the show :)
Thank you to Cameo for making a cameo
