Cats have evolved as the "predatory hunting animal" equipped with great agility and keen senses. From almost the very start - a kitten of all species of cat shows instinctive behavior typical of hunters. Just like house cats, lions spend a huge amount of time every day licking themselves clean. It’s not just because they’re fastidious; they’re working to remove as much of their scent as possible.Yours isn’t the only cat that lounges around from morning to night. Domestic cats usually sleep between 16 and 20 hours a day; lions average right around 20 hours daily. And just like house cats, lions prefer sleeping during the day, becoming much more active right around the time people head to bed.Everybody has heard about the saber toothed tiger. As you know the saber toothed tiger is most known for his large canines. As a matter of fact they were 20 inches or longer. The Saber toothed tiger however is NOT related to the modern day cat. The saber toothed tiger died out about 30,000 years ago.
