We have 1″ galvanised wire mesh on our run. Next year’s project is to extend the run further. Thing is cats are still cats, so need stimulation, so you need stuff for them to climb inside if an indoor cat. Our run has lots of ledges, walk ways and slopes for them to run about. Also has cat friendly plants and herbs in it. Part of the run takes them along the back of our fence, with views over the fields.
The older cat, doesn’t go in – she isn’t bothered – she goes out. Ragdolls are known to be a bit ‘stupid’, our last was quite clever, but a cocky bugger, and that is what got him run over – he was quite a distance from the house, much further than our ‘moggies’ had ever been, and he hadn’t been out until after he was ‘done’.
