Cat Nebula

Jerry and Nibbles (Tuffy) are in a space ship. They are running out of food, due to Tuffy's eating habits. Finally, Jerry manages to find some dehydrated energy capsules, but he swallows an entire year's worth and grows enormously overweight. Then a doctor, Droopy, comes to check on Jerry. Later, an alien space cat, obviously similar to the appearance of Tom, wants to eat Jerry, and they end up running around chasing each other on the ship. Finally they are launched from the ship's torpedo and apparently killed by the explosion, as they have become constellations in the sky with Tuffy saluting them.
