I have two indoor cats, Gawain and Edgar. Gawain is 11 years old and Edgar is around 6 (we think). We feed them together, but Gawain gets special, canned food because his kidneys are failing. Edgar gets dry food, and occasionally canned. Edgar gets very jealous when they’re eating and tries to take Gawain’s food. I push him away, hit him lightly, and yell at him, but he doesn’t stop.
