Hello:

For a house that has natural gas for heating, as well as the cook stove:

Was wondering if there are natural gas detectors (guess it's Methane) one
can perhaps place
in the basement near the furnace, such as there are for CO detectors ?

Probably as worried about a natural gas leak as I am concerned about the
possibility of excess CO.

Looked on the web, but could only find a model made by:
Safe-T-Alert (40-411) who I have never heard of.
Any good ?

Does Kidde or First Alert make these also ?

Any thoughts and opinions on these types of detectors, assuming they
exist,
would be most appreciated.

Natural gas has an oder added to it so you can smell it. It is also lighter
than air so it will rise. Propane gas is heaver so it will collect in the
lower areas of your house.

Here is one to check out. I don't know anything about the company or
product, just did a search for the gas detectors.

Where I work I calibrate some portable detectors that check for various
gases. The LEL is where the gas will burn or explode. The warnings the
alarms are set for are from 10 to 25 % of that level.
