I’m in the process of putting together an outdoor cat enclosure and I’m struggling to come up with some cost effective ways to provide my cats with stimulation. This is the enclosure I’ve used, but instead of the standard plastic chicken mesh I’ve used snake/mouse mesh.

I’m hoping y'all could help me come up with some lightweight and weatherproof ideas (and how I can implement these). So far, I’m wanting to add in:
- Cat friendly, frost tolerant, plants.
- Shelf and bridge set I’m not sure what the best way would be the attach this. The enclosure posts are 2m apart, so the brackets won’t line up, and all I can come up with is cable ties and rope but I’m not too sure how sturdy this will be?
- PVC pipe with sisal for scratching posts. If I can come across any fallen branches I’ll do the same for a more organic look. This is looking to be an expensive task as 20m of rope only covered perhaps 30cm of pipe.
- Pine boards for ramps, but I’m unsure how to secure these and how to weatherproof.
- Outdoor canvas material made into hammocks. Hoping this one is straight forward!
- I’d love to implement some platforms and bridges, but again am struggling to work out how to secure these.
Any suggestions and insight would be greatly appreciated 🥰
