According to www.answersingenesis.com:
The tiger is from the ferocious “cat” type. It is very easy to spot by its beautiful color and coat. Its striped fur provides a wonderful and clever way to hide in tall grass like savannah or among the trees in the forest.
Every single tiger has a different stripe pattern.
Tigers talk with each other by rubbing heads, roaring, purring, and grunting.
Tigers sleep 16 to 20 hours a day. They love to lay out on a rock and take a nap in the sunshine.
