Bag of Cats

This ordinary bag made of grey, green, or tan material. It has a series of runes written around the opening at the top, which appear to any expert in reading runes as just gibberish.

The mouth of the bag is drawn closed with a drawstring. The bag occasionally moves slightly, as of something alive is inside. As an action a player can pull from the the bag, a common house cat. This action can be repeated once every 5 minutes. The cat's breed is determined by the table below:

The cat looks like an ordinary cat, but is actually an ethereal being. After 8 hours, the cat will cease to exist. The cat's cannot obey commands of any kind, beyond being encouraged to go back into the bag. The bag is always accompanied by a single, real living cat that will follow the owner of the bag with interest. Roll the table to see what kind of cat this is, or just choose the one you'd prefer.

If a roll above 90 occurs while rolling for a cat  it instead produces a Displacer Beast. This beast will join the party until the next battle they have. In combat it has it's own initiative and is commanded by whomever let it out of the bag. The beast will cease to exist after the battle. This effect cannot occur more than once per long rest.
