Pros & Cons of the 40 Gallon Breeder Glass Tank

✅ Pros

  • Excellent floor space for hamsters
  • Deeper than standard tanks — supports 6"+ substrate
  • Escape-proof
  • "Breeder" proportions maximise floor area vs height

❌ Cons

  • Heavy (~55 lbs empty)
  • Requires a secure mesh lid
  • Limited vertical enrichment options

What Rabbits Need in an Enclosure

Rabbits should ideally be free-roam in a bunny-proofed room or large pen. Traditional hutches — even large ones — are considered inadequate by modern rabbit welfare standards. Rabbits need space to run, binky (leap and twist), and stretch fully. At minimum, provide a large pen with free-roam time of 3+ hours daily.

⚠️ Things to Avoid for Rabbits

  • Traditional hutches — typically far too small
  • Cages with wire floors — causes sore hocks
  • Permanent confinement without daily free-roam time
  • Keeping rabbits outdoors without predator-proof protection
  • Isolating a rabbit alone — must be bonded with another rabbit
