For our cat, we have some grass in flower pots on the windowsill. I don't have the package with the seeds any more, it said something with cat grass.
On some of the blades, there is some white fluffy stuff:
The soil is flower soil from the hardware store. I try to water the “plants” every day but sometimes forget. Sometimes they had a little too much water and were sitting in a little puddle that got soaked up eventually. The pots are directly next to the convection heater.
Is this something to worry about? Does it cause any health problems to us or the cat? Is there something that one can do against this?
