Kif, Priya and Raj (2)
Kif lived with Priya and Raj for another year, before he succumbed to liver failure. He died mid-January, the year after Leela died.
Priya and Raj
Priya and Raj continued on - although Priya was a bit too fearless, and she got hit by cars on at least three occasions. The first time, she was just in shock, and recovered on the way to the emergency vet. The second time she had to have her tail amputated (the collar didn't stop her escaping through the cat flap one day). The third time was the end, and she died late January the year after Kif died.
