I just thought I might explain this....
So recently lots of people have realised that non deafult eyes become worth more, because of this people are buying lots of x eye pets in hopes they will become rare in the future.
But literally every single person is thinking like that, buying a couple x eyes or sumthin.
This means that for pets like guine pigs x eye ones are just gonna be super super common, as so many people have bought them.
The reason why the x eyes are rare is because people didn’t buy them, not because that eye type is automatically more rare.
(This is only applicable to pets that have come out recently and in the future )
