When you add an item to your wishlist, it goes into whatever category you have selected as your Default wishlist category. You currently have your Pets category selected, so that's where the scissors have gone. You can change your default from the main wishlists home page.

For future reference, if you are not sure where an item is on your wishlist, you can search for it using the search box at the top of that page. It will show you what category the item is in if it's found on your wishlist. Hope this helps!
