Cats vs Houseplants

Do you have cats digging in your houseplants (and using them for a litterbox)? Try spreading a layer of rocks over the soil to stop them from doing this.  You can even add in a few of the flattened glass beads from the craft store to give it a splash of color!
The kind of rock doesn't necessarily matter.  Most any kind that takes your fancy should do the trick.  If your cat is stubborn, however, and continues to dig through the rocks, then switch to lava rock, which you can usually find at your local home improvement store.  Cats don't enjoy the abrasive feel of the rock on their paws.
And that's usually all it takes.  Happy gardening (even in the winter)!
