ok well im sketching out the cage im gunna be building my bp... shes almost a yearling now and i wanna have something that she wont grow out of. so far from what ive read on here about others custom cages is that a 36'' long by 24'' wide and 18'' tall seems to be average- it works out to about 68 gallons - but also from what ive read a BP can live in a 20 gallon long for its life..... so would a 3' x 2' x 1.5' cage be too big ... if there is such a thing ??
