    The commercial in the middle ruins the continuity. If you must have it, but it at the beginning or the end

    This was so much funnier because my cat was giving demonstrations the whole time. She was sticking her whiskers up my nose when you were talking about whisker vision (probably just checking for boogers). She was licking the tender skin off my chin while you were describing the tongue. And then she turned around and put her eye of sauron in my face at the end when you were talking about getting behind the tiger. I laughed until I cried.

  11. Jude Manalac says:

    what's happening on the crocodile crotch at 6:36 ? is it giving birth? shitting before it got pounced? aroused? it seems inflamed what was that

  12. Not so shure about that Flehmen Response to all species pictured are correctly assumed by our science. Our bulls, sheep bucks and stallions did that + upper lip thing 7:33 only when they got smell of females in heat. Thats how we made sure of cows ovulation before inseminations. I never observed same in cats for the same reason though. That lion male 7:11 throws a nasty grin reaction proper to the smell signature of catpiss markings of other tomcats same as my boy felidae did when strangers had marked his private stairs, etc. In difference to our bulls and bucks, he does not seem happy news mode at all.

  19. "Trust me, I could drink beer out of a bucket in the dark"

  23. 6:36 that aligator is packing some heat.

  24. Trapsquad says:

    Why does YouTube only give you one ad or on some video no ads they really suck I can’t wait until the next best thing comes along and ppl and freely make content and be paid for it this shit is hilarious and factual

  25. Ok but can we please get a full release of Beer from a Bucket in the Dark? It's such a vibe

  36. irishgrl says:

    Only the domestic Persian has fur too long and dense for effective self grooming. You can kind of tell.

  37. karmakazi219 says:
