weird stains showing up

Hello!
The carpet stared showing dark spots after about 2 - 3 years. No spills or pet spots (yes we have two cats but they use the litterbox). The carpet is installet on concrete. Moisture should not be a problem as New Mexico is pretty dry. There has been carpet o n the concrete before - so the concrete is old - so it should be dry enough. Please advise.
Thank you very much, Sarah

Stains on tips of fibers usually indicate something that has been tracked onto carpet. Stains in fiber tufts usually indicate a spill or something wicked up from below.

If carpet has jute backing, it is possible for vapor emissions from concrete to cause breakdown of jute and browning of carpet. Rebond pad can cause yellowing of olefin carpet and nylon stain resistant carpet. Break down of jute and natural fiber carpet cushion can cause staining of carpet.

Did they install the new carpet, over existing padding?
