Why humans cant see fairies

Wow, after a long time, I finally got some time to spare on myself! and wanted to do something good, but... this is the first thing that popped in my head that time! xD, it's a weirdo thing but... let me explain with this story that I'm just about to invent:

Cats are very greedy and jealous of magical creatures, so they're always in hunt for some magic for themselves, by eating those creatures.

So... Why we humans cant see fairies?
Because cats find them first.

Maybe you can recall of their nine lives and their alliance with witches.

Ok! Another of my super lame stories so don't read! xD, but hell yeah this was relaxing =3=
