All the items in my shop have been handcrafted by me with love, patience, and a bit of frustration here and there :) All items come from my smoke-free, one-kitty home. I make every effort to ensure that my items are as clean as can be, and I take particular care with those items intended for infants and young children. However, if severe allergies are a concern in your household, you may want to consider looking elsewhere, as I cannot guarantee that my products are 100% free of cat hair.
