As I am having to let my canaries and Greenfinches go, I no longer need my all wire breeding cages.  I have 10 cages & 10 trays, and a number of end panels / joining panels.  The dimensions are 59cm L x 31cm D x 40cm H.  I have bought spares for these from Moondown Farm (https://www.moondownfarm.co.uk/?store-page=Breeding-Cages-Accessories-c127336306)
