I had a parakeet that got sick circa 2007 and the first thing the vet asked me was, do you buy bird seed from China. I didn’t and the problem wasn’t from that, but it goes to show you that Chinese pet products of all kind have a terrible rep.
Yes they do. I buy expensive cat food from PetCo that's labeled Made in USA, but wish I didn't have to spend so much. Hope your parakeet recovered.
