Bar Spacing & Bumblefoot Check

Two classic housing problems in one pass: bars wide enough for a rat to escape (or get stuck), and wire floors that pressure-injure footpads into bumblefoot. Enter your cage details for an escape verdict and a bumblefoot risk score with a fix list.

Cage Details

Quick conversion: 1.2 cm = 12 mm · 1.7 cm = 17 mm · 2.2 cm = 22 mm.

Adult: >12 mm risk begins · >17 mm high · >22 mm certain escape. Juvenile (<8 wk): >8 mm risk · >12 mm high — babies can squeeze through astonishingly small gaps, including floor mesh.

Bumblefoot Risk

Band

Score = wire-floor coefficient × soiling factor (≤3 d 0.6 · 4–7 d 1.0 · >7 d 1.6) × weight factor (>500 g 1.3) × bedding (cedar/pine +15%). Bands: <0.3 low · 0.3–0.7 moderate · >0.7 high.

Fix List

  • Replace a wire floor with an acrylic/solid panel or cover it with thick fleece/paper bedding so feet never press bare wire.
  • Spot-clean urine daily — wet, soiled bedding macerates footpads and lets infection in.
  • Provide at least 1 solid shelf per rat so everyone has a wire-free resting spot at the same time.
  • Check feet weekly for pinkness, redness, small scabs or crusts on the pads; early changes reverse quickly.

Home Care vs Vet Line

Home care (5–7 days)

Pinkish, mild redness with no swelling: move onto soft, clean bedding, add solid surfaces, rest from climbing, and inspect daily. It should fade within a week.

See a vet

Swelling, crusts/scabs, limping or bleeding: bumblefoot needs antibiotics and pain medication — it can become chronic once footpads are deeply infected.
