If you are having trouble with your cat always eating your plants or digging in the soil there are several easy solutions to this problem.
Cats naturally like to explore their territory, and your plants are included in that territory.
So if you are tired of cleaning up topsoil off the ground here are some ways to save your plants.
If your cat is always playing with plant soil you could try putting some large pebbles or rocks on top of the soil.
These will be too heavy for your cat to move, but at the same time allow water to pass through them so you can continue to water them.
Another solution is putting some pinecones on top of the soil.
Cats do not like to touch them or step on these.
As a last resort you could try putting aluminum foil on the top of the soil as well.
Cats do not like the feel of aluminum foil and you can poke holes through the foil so you can continue to water the plant as well.
If your cats are chewing on the leaves you can spray a product called Bitter Apple on them as well.
If your cat really likes chewing on plant you could invest in buying some cat grass which is sold at most pet stores or online.
This allows cats to chew on plant material, and will hopefully divert their attention away from your plants towards her own cat grass.
As a last resort if none of these steps seem to work for you can always elevate your plants higher or put them on a pedestal so they're not reachable.
