Here’s my template I use for my cat amigurumi!

Pattern is for the basic cat body and a fluffy tiger. You can mix and match however you like and use this as a jumping off point for other types of felines!

Materials:
3.5mm hook
9mm black safety eyes
Yarn sewing needle
Polyfill
Optional wire brush to brush out the fur
Worsted Weight Yarn (gauge is not important so long as you use the same weight yarn for all of the parts)

I used less than a skein of the following for one cat:

Red Heart Super Saver Aran with Flecks (42 yards total)

I used less than a skein of the following for one tiger:

Body: Big Twist Orange (57 yards total)
Stripes: Red Heart Super Saver Black (16 yards total)
Belly and Mouth: Red Heart Super Saver White (6 yards total)
