A few minutes of searching and you should find it- there are so many different locks. Yours is likely to be a spring loaded lock which I have seen before when helping others find cage locks but I do not have time to search this morning sorry.Thanks, I am looking but would like the same one I have - I hope I can find it difficult..........
The title was not changed perse. The thread was posted twice with two different titles. The other one was deleted so as to keep the replies together.Apparently the title was changed. I know it read "Avian Adventures Cage" before. I searched for the part, but could not find one.
If the spring is broken perhaps you could locate a new spring.
