Kitty Cat to Birman
Activate 2x coins. Get a Somali Cat. Now, the Shop has opened up. Buy lots of Kittens, and work your way up.

Birman to Bombay Cat
This is where it gets complex. We will be exploiting the fact that when a new cat is unlocked in the Shop, it is EXTREMELY cheap. That is GOOD. Very good. Now, we are in a loop. Cats > Coins > Cats. Now, let's get mathematical, to determine the rate of progression. So, let's say we have a Ragdoll. We have a Sneaky Cat unlocked. Our friend, Sneaky, is 5 tiers below Ragdoll. Seeing as Cat Condo is a merge-2 incremental, that means that 2^5 Sneakies are required to unlock Japanese Bobtail in the shop. 2^5 is 32, so the progression is pretty slow, huh? Well, fret not! Gift and Surprise boxes are good, and also, we have 2x coins, which makes it approx. 1/16! **TBC**
