[Bagzoo]

With the rich I am blue,
with the poor I am red,
with the amphibian I am cold
but with the dog I am hot instead,
what am I?

"Blue blood"
Red blood (unsure about this connection)
Cold-blooded amphibian
Warm-blooded mammal

So, 'blood'.

[Aramina]

How many cats can you put in an empty box?

[Rita G.]

None, because then the box wouldn't be empty.

[GypsyWitch]

One cat, and the box is no longer empty.

[Aramina]

You are good

I am a container with no sides and no lid, yet golden treasure lays inside. What am I?

A credit card

[Scoozie]

A gold coin
Or maybe a gold mine

Hahaha
An EGG!

[fluffdragon]

An egg.
