My three dogs:
Elmer, Muddy, and Scooter are all fixed..
My two cats Oreo and Boots are both fixed too!
My goldfish aren't... lol
my Iguana isn't either but he doesn't come in contact with any other Iguanas anyways
I had a hard time neutering my dogs because I couldn't afford it.. however I bought less food and watched the bills when I got my last one (Scooter) because it is pure torture to let an animal go unspayed/neutered..
I hope everyone knows that...
