Having a heart
A domestic cat's normal heart rate ranges from 140 to 220 beats per minute, depending on how excited the cat is. For a cat at rest, the average heart rate usually is between 150 and 180 bpm, about twice that of a human (average 80 bpm)

To Skin a Cat
Cats have loose skin, even if they are not fat. This is to help them turn and confront a predator or another cat in a fight if it has a grip on them. This looseness is also helpful when vets have to give cats injections

Doggonit! The Dog has been domesticated for around 15,000 years. It has been said that because dogs and humans have lived together for such a long time, this greatly improved the chances of survival for the early human groups, and that the domestication of dogs may have been one of the key forces that led to how we are today. Over the centuries the dog has performed many functions that have helped man in his earliest settlements to the complicated tasks they perform nowadays. It is because of this versatility that the dog is known as 'man's best friend'. Dog demonstartion c/o Pawsability Dog Traing: Agility, Obedience and Dog Behaviour

Sleek Not Slow
Slow worms are not snakes but legless lizards. Although they are often mistaken for snakes, you can recognise a slow worm by its blinking eyes (just like a lizards' eyes which are different to those of a snake) as snakes eyes don't blink as such. Slow worms shed their skins in patches, like lizards do  whereas a snake will shed its skin all in one go. Slow worms can regrow their tails, snakes cannot. In the wild a slow worm can live for up to 30 years, but if in captivity they can live for over 50!

Daddy Long-legs?

The tiniest spider in the world lives in Borneo and measures 0.37mm (0.015 inches) in length.   In the UK and Ireland (and Portugal) money spiders are so called that if one of these tiny spiders ran across you - it had come to spin you new clothes, meaning good fortune for you. Crab spiders can walk sideways and backwards.
