Best bird bath on the market! Fits at any level on any cage bar, and holds firm. It is solid for the bird to land on with a rounded edge which makes a great perch. This bath is clear so the bird can see the water, and shallow making it easy for a bird to flap and duck to have a fun , safe bath( like having a bath in a puddle.) Made from a durable hard acrylic which can be sterilized. Best for budgies, Cockaiels, Parrotlets, Canaries, Finches, Conures, Senagals, and all similar sized birds.
