No worries! Another thing to consider (if you have a water shortage problem- our whole country is nearly in drought) is if you put in near something that needs a bit of water, when you empty it throught the drain hole, the water & poo will seep into the ground and be absorbed by nearby plants...
Oh, we tried that too, but rocks (even the flattest ones) tend to have a way of creating tears too..You may have more success though..If you try it, get the toughest grade liner u can afford..
Another alternative; I ended up buying a sheep water trough, it is about 1.6 metre diameter & 60cm...
Hi!
We tried building an inground pool, but their sharp little claws destroyed the liner and it leaked! Now we use a food storage bin (the big plastic ones) cut in half lengthways..
Just need to be careful that it was used to hold food, not chemicals or poisoning can occur..
Happy...
