Dog Meets Cat — a Really Big Cat

April 18, 2017

Dogs love to chase cats — but maybe not if the cat weighs over 600 pounds! In this video, a little Jack Russell Terrier meets a Siberian tiger. The dog sure doesn’t chase the big cat, but the tiger doesn’t chase the dog either, or roll over and squash it. They just bat each other playfully with their paws. It’s a pretty silly friendship: Jack Russell Terriers weigh between 13 and 17 pounds, while tigers weigh anywhere from 200 to 675 pounds! Also, that tiger’s 3-foot tail is longer than the whole dog, who is at most 15 inches long. If you had to pick one as a pet, the dog is probably the easier one.

Wee ones: Tigers and dogs all have 4 legs. Get down on your hands and knees like a tiger, then pick up your front left “paw.”

Little kids: If you ran in there to play with the tiger and dog, how many legs would you all have together? Bonus: How many more paws than feet would there be? (People have feet, not paws.)

Big kids: The dog’s exact weight is a secret, but if you double it and add 4, you get 30 pounds. How much does the dog weigh? Bonus: If a tiger weighs 400 pounds, how many tigers together weigh a ton? (Reminder if needed: A ton equals 2,000 pounds.)

The sky’s the limit: If all Jack Russells weigh 15 pounds and the tiger weighs 600 pounds, how many Jack Russells would have to pile up to outweigh the tiger?

 

 

Answers:
Wee ones: Lift your left hand!

Little kids: 10 legs. Bonus: 6 more paws, since there would be 8 paws and just your 2 feet.

Big kids: 13 pounds, since the doubled number would be 26. Bonus: 5 tigers.

The sky’s the limit: 41 Jack Russells, since 40 of them would weigh exactly 600 pounds.
