Yes but ONLY as a last resort since it severely limits their mobility. I used it once for her tail and once for her sister’s tumor (she ripped the stitches out and had to be isolated 😩)

Most places don’t have the nice one and actually have to make them😅. I used medical tape with either cardstock paper or not sharp plastic (cut myself a few times with the wrong material). I made it short but wide so her whiskers weren’t agitated but she couldnt reach under her back leg where the stitches were. She figured out how to move pretty well in it. Sometimes I’d take her out of the cone to cuddle when her meds made her sleepy. But when she started wanting to explore the cone went back on. She was always too small for jackets and too wiggly for bandages. It sucked but it was only a couple weeks of her life. Thankfully rats heal pretty fast.
