I have the same issue with one of my foster kittens. We tried different types of cones but they only stressed her out more. Finally, I did a search online and found a product called Suitical, a suit that resembles a baby onesie but made for cats. It completely protects the surgical area and has a cutout around the rear allowing for litterbox use. So far, the kitten is doing well and is healing properly. Hope this helps.One of my temporary foster kittens is sucking on her stomach where her stitches are (from being spade). Is this normal? Could it cause problems?
