A friend told me about buying a great product to keep cats off soil and gardens from a shop in Plaza Singapura and so I went down to get it today. It turned out to the the Daiso on the fourth floor. I know E_Cat has also bought a similar product at the branch in IMM. This will be great for Mediations.
These little spiky mats are $2 each and as you can see, there are two different sizes. One is for flowerbeds, and one for larger areas. I bumped into an old classmate while leaving, and she immediately recognised "Don't Cat" and said she had been using it to keep her cats from jumping out the windows.
If you are considering buying some, the section is near the far corner of the shop near the Garden Supplies. Look for the rack with hangars, and it'll be at the bottom - the two staff I asked didn't know where it was.
