REASON

This is my new theory of Corgi-Cat Compatibility: 

Not all cats have stripes (like Tigger has). 

Some cats are sort of friendly (like Tigger can be). 

Therefore; polk-a-dot cats are a moving target.  

See my Zenn diagram -- 

(the secret is I find lots of colored markers on the floor) .

P.S.  I'm still working on the conclusion to that logic problem..
