Even though I'm not a huge Betta fan, I signed it because I think every kind of animal cruelty is wrong. I also think that spamming their email isn't going to get you anywhere.
I don't mean to be rude, but there are some spelling and grammar mistakes in your bit above the link to sign the petition, where you address the company. Please don't take this the wrong way, but perhaps if you corrected these, the comapny will be more willing to listen. It will look more professional, and if you send it with mistakes, the company will probably laugh at you. Please don't take that the wrong way.
I wonder who buys these sick purses?
