Kibble of Life
The Kibble of Life is an aspiration reward that was introduced in The Sims 2 expansion pack Pets. It looks like a pet bowl, but a bit fancier, as it has five "jewels" on it. (Each "jewel" indicates one of the five uses it has.) It's a pet's version of the Elixir of Life, and like that elixir, it gives off a green glowing color. Unlike the human elixir, it only works twice in a pet's life, once when the pet is an adult, and once when the pet is an elder. However, it will never fail and make the pet older.
