Frequently Asked Questions
Why does bar spacing matter?
Bars that are too wide allow birds to escape or get their head stuck; too narrow and larger birds cannot perch comfortably.
Is bigger always better?
Yes. The minimum dimensions are welfare guidelines — a larger cage always benefits the bird's physical and mental health.
Is it free?
Yes, all calculators on OhMyCalc are completely free.
