Mammals

Cats spend about 70% of their day sleeping — that’s about 16 hours!

Dogs don’t need to chew their food as thoroughly as humans because their digestive acids are about three times stronger than ours!

A cougar kitten is about the size of a guinea pig when it’s born!

Lions are not afraid of water and will readily enter rivers or lakes to catch prey or cool down.

Kittens start walking when they’re about 3 weeks old!
