Hello! I rescued about a month ago this cactus from a neglected garden.

I noticed this white fuzz and I dont know if its part of the plant or a disease.

Could you please help me? It is the first time I adopt a cactus hehe.

Part of the plant.

Some cactuses, especially Mammillarias are naturally fuzzy to an extent. Smiling

People sometimes call mammillarias "snowball cacti" because of the natural fuzz they get.

So nothing to worry about, they're just growing the way they're supposed to!

Fun fact: in addition to fuzz, some Mammillarias (like yours) also produce bristles in the same location:

The bristles are like spines, but in a different place, usually a little softer, and characteristic of many plants in the genus. The spaces in between the tubercles are also where flowers and fruit emerge, so don't be alarmed when you see more strange growths coming out of there. For example:
