5836 en <p>AniWares was launched in 2012 to develop animal themed products for the little ones in your life. This company was created by me, Anita, a health sciences project manager who was inspired by my son, Griffin, to form this company as an outlet for my creativity. When Griffin was born, I decided to stay at home to care for him. As his needs grew, Aniwares grew. He is 10 now and AniWares is focused on crochet work as it has always been a favorite!<br><br>In 2015, we also started a FurBaby Collection of hats so that we have something for FurBabies!<br><br>All our products are handmade by me in sunny San Diego, California.</p> <p><strong><span style="color: rgb(0, 0, 0);">Thank you for visiting AniWares!</span><span style="color: rgb(192, 80, 77);"></span></strong><br><br>Please note that products are handmade and a few discrepancies may exist between the product photographed and the product shipped.
