Having worked at a vets, the last thing I would want to do is give a cat an enema. An angry cat has weapons all over the place, and frankly, I would think a cat getting an enema might be an angry cat.
my cat is a mean mean sob. When we took him to the vet he had to get muzzled. The vet got the muzzle on him but not before he bit through the vets heavy gloves. I love my cat but I can’t imagine anyone being capable of giving a cat an enema without sedating him or getting sent to the ER.
