Yes, Jolana. It's tedious to drill them, but I do it. I had to drill one in the bottom of a ceramic pot this week. It's done and I have the plant, but the plant is still in the plastic container. I'm sooo slow sometimes. I've taken to making the slings like the other one in the background simply because it's faster than drilling.
Here are a couple taken Saturday. I think it's the same one, but it's pretty much grown now and I have an extended family hanging around
and I can't really tell them apart. They graze on a couple of potted plants, but mostly they just eat grasses in the yard. These were taken about 15' from where the one posted earlier was taken. They are so goofy! I could take photos every day if I would carry the camera around.
