When Moriarty arrived, he came with a corner platform perch in his cage. Though he has since moved into Dalai’s old cage (the Silver Villa), he still spends time in his old cage every day.

The platform perch in there is one of his favourite spots, especially for a nap.
He had chewed down the rim at the part where he rests his head, which in itself is not a problem, but a little further along, a nail of unspecified metal was exposed. I thought, it is time for a new, safe perch. I did some research to find a perch of the same, or nearly the same dimensions, & ordered a custom made one from The Natural Bird Product Company (https://www.naturalbirdco.co.uk) who craft natural perches & toys by hand in the UK.
It arrived on the 2nd July. It took me a while to get around to installing it as although the new platform perch slotted through the small Ferplast Canto door, the old one did not. I thought it might come out through the bottom tray but that area is heavily padded so it was actually easier to take the top off the base & get the perch out that way. It was a good opportunity to give the cage a thorough clean too.
The only worry about acceptance was that the new perch is slightly shorter than the old one. Stupidly, I forgot about one side being 1 cm shorter, & installed it with the short side along the front. There was about 1.5 cm difference with the old perch along that edge. Moriarty took to the new platform perch quickly, but for general purposes only…

He struggled to find his old napping position on the severely shortened length, often looking like he was going to tip off the edge…
He resorted to napping in different places…
Seeing his struggle, I remembered the new platform perch had a longer side, so I flipped it around & for good measure, also threaded through a wooden slat (0.6 cm thickness), bringing the perch closer in length to the old one.

Balance in Moriarty’s universe was restored. He was back napping comfortably on the platform perch in no time!
