Here are a few interesting science facts about our domesticated cats:
1. Cats are obligate carnivores. They must eat meat because they require two amino acids to be presynthesized by grain feeding prey. The cannot convert it themselves. Any cat food that has vegetables or grain in it is practically useless for them.
2. They have a spine that is flexible in more than one direction.
3. They have a second layer called tapetum lucidum that lows them to see in the dark by reflecting available light onto their retina. It's mostly Grey tones and they don't have night vision if there's no light source.
4. Their tongue has tiny hooks that bend backwards so anything they lick or groom goes down. One way only.
5. They can't spit.
6. They can breathe and swallow at almost the same time. Humans cannot. (When humans swallow they stop breathing for a few seconds).
7. They slice/saw their food like a shark and don't chew since they have no molars.
8. Their communication is nonverbal body language. The "talking" is learned behavior for us.
9. They heal much faster than most mammals.
10. They purr when they're content or distressed. Lots of theories about that.
11. They form communities when feral, but don't have a hierarchy.
12. They can't sweat. They cool off through panting and their fur traps cool air in the summer.
Incredible amazing creatures.
I will add some more facts as I think of them
