The other cage shes in now has the correct temps. If I put her in another sterilite tub while I put the heating together and get the temps semi-close, would that be ok. Also I drilled the holes last and went with one row all the way around 3" apart and 1/8" in diameter, Its on a 56 qt sterilite. This doesn't seem like a lot of room for ventilation, did I do it right.
