creature comfort...

[light]

hi,
what does 'creature comfort' mean? I came across this in different contexes.
Some are about vets or pet centers. Some are totally different.
What is the origin of this term?

[Tdol]

Creature comforts are things like food, hot water and warmth that make life comfortable.

OK. comfort is easy to understand, but I can't figure out 'creature'.

[Tdol]

They're basic animal needs, which distinguishes them from, say, the internet.
