We had a previous cat containment system for our yard that wasn’t working for our newer cats - a beautiful stray cat we found in the wilderness and her three kittens. We needed to replace it, and so we removed the non-functioning old one and ordered the catnetting system.
Installation required some special considerations at corners and gates, something that wasn’t in the instructions and we needed to puzzle out, but we did get great and quick help from their support staff. It took a while to install since there are a lot of pieces, but I was very impressed at how well thought-out and flexible/durable/robust the system was.
Unfortunately, once it was up it kept our cats in for about three minutes before they figured out how to escape. (We were of course crestfallen, but had expected as much.) That’s probably not the case for most people’s cats, but our cats - especially our male and the mother cat - are very athletic and smart, and they’re very hard to contain.
To make a long story short, we augmented the system with several new refinements after every escape. We were able to do this primarily with surplus materials provided in the catnetting shipment, as well as a couple trips to the local hardware store. Now our cats are fully staying in the yard - here’s hoping it stays that way! (I plan on contacting Catnetting to give them some tips on how we managed to contain our escape-artist cats - hopefully they can make that available to everyone.)
