It's actually spurisingly spimple!
For the head, you take a cat and add on mammal ears of your choice (or weird round spikes)
The neck? Take a snake or ferret and add extra fur and floof.
You will need a fat, hairy skeleton for the body that is actually composed of goo. whilst for the legs you shalt need claws. probably berdsclaw work best.
And finally, the volumptous tail! I just took inspiration of a snake and it worked out wel : }
hap drawing!!
