How did he become a fennec?

Voluntary process. Months floating in a 'tank' while being changed

Yep, fenfens are both adorable and loud

Aw... think someone needs a few lessons on how to be a fennec. I could offer some help? First off, they aren't folding ears back for loud sounds. Can also put hands on top to help with things a bit more.

If you think the screeching is bad, they also do it when they are happy, just not as loud. Then there is getting used to being called a pokemon and all the comments about the ears. ;)
