I'm thinking about selling some crochet creations on Etsy. I have a dog and a cat in my house. Since you have cats, I thought I'd ask your opinion: do you think it's a good idea to mention that the item was made in a dog/cat home in case the buyer has allergies?
I think it's definitely important if your animals or their fur come in contact with your products. I work in a room where my cats have never been allowed, always keep the door closed, wash my hands before I start to work on my handmade products or package them for mailing, and keep all of my materials and finished products closed in clean plastic bins in order to keep the cat hair out. That might be tougher to do with crocheting, since when I crochet or knit for fun, the yarn or piece I'm working on often ends up draped in my lap or on our couch (which the cats do sit on), so you may want to include that in your shop information to be safe.
