Catio or Aviary Panels (Keresley Newlands CV7)

I would like to give my special needs rescue cat Jiggly (he’s deaf and partially sighted and has a traumatic brain injury) and his siblings more room to roam around outside in a safe space. I’m looking for wire panels to be able to extend the small one I’ve already managed to build. If you are dismantling a Catio or Aviary please consider me.
