Rabbits are able to see nearly 360 degrees around. This is because their eyes are very large and are situated high on the sides of their head.
Cats spend at least 1/3 of their time awake grooming themselves, and grooming begins within minutes after birth. While this might seem a bit obsessive to you, grooming performs several important functions: it cleans their coat, helps regulate their body temperature, and relieves anxiety.
If left unspayed and unneutered, one pair of cats and their kittens could produce as many as 420,000 kittens in 7 years time. That is an average of 60,000 kittens per year!
More than 5 million new puppies are born in the United States every year, and many of these dogs will have multiple litters of their own puppies.
Cats are designed for hot climates. Provided they have plenty of clean water to drink, cats can tolerate temperatures as high as 133 degrees Fahrenheit.
How often do you hear your cat meow at another cat? Cats typically only meow at humans; they purr, hiss, or spit to communicate with other cats.
If you think your cat rubs against you just to tell you he loves you, think again. The real motive might be slightly weirder; cats rub against people to mark their territory with scent glands located in their face.
Puppies grow a lot during their first few weeks of life. In fact, to promote growth, a newborn puppy spends 90% of its first week sleeping and 10% of its first week eating.
