The cone's job is stopping licking and biting; the classic hard cone protects most reliably at the cost of eating, drinking, and stress.
Inflatable and fabric soft collars are more comfortable, but flexible cats can reach hind-limb and tail-base wounds past them, so suitability depends on wound location.
Abdominal incisions such as spays can use recovery suits if they fit snugly, breathe well, and cannot be flipped up, with daily wound checks at changes.
Clear any alternative with the operating vet first; if the wound reddens, oozes, or stitches get pulled, restore reliable protection and return to the clinic.
