I'm sure there's another thread about this but I guess I'm blind tonight I'm making my husband build Dolly a new cage before he deploys. I don't have the first clue on what to do. Thought maybe you'd like to share designs, advice & whatever else. How do I know the materials are safe? Is there a certain kind/brand? I'm also wanting to make her a pretty big cage. Her toys are overflowing in hers now (She's extremely spoiled) Is there such a thing as to big when it comes to their cage? Sorry for all the questions, just want to make sure I don't cause Dolly any harm
