When I hosed cage, some colour ran off a newly purchased toy, (orange, red, yellow and green wooden balls interspersed with plastic discs). Hubby said that it was probably a food colouring but wondered if maybe it was something not quite so safe. Purchased from a major chain store, but not much info on the packaging. Of course, I should have taken it out of cage first, but then it had to be washed at some stage, even by hand. Any suggestions, please?
