The Chimeric Spider Cat is another ill-advised creation of the Black Star Chimerists. At first glance it typically resembles an ordinary house cat in size and shape. White long-haired cats seem to be the most common.
On second glance, it becomes obvious that the cat has many more legs than it should, and these legs are spider like in nature. The spider cat has a climb speed equal to its movement speed, which horrifyingly enough is near twice that of a normal cat.
On third glance the spider cat is probably leaping into your face, legs extended to grapple your head as it claws and bites you to satisfy its unnatural hunger. Once the cat has taken damage, it may attempt to flee using its small size and natural stealth to get away, or it may use a bonus action to grow in size equivalent to a giant spider (large c reature) and continue the attack.
Use your fourth glance to look around, because while they may be solitary, Chimeric Spider Cats have been known to run in feral packs.
