Juno & Jinty are sisters.
Poor Juno.... Hatty, you may find the cast doesn't stay on for more than 2 weeks. I had a similar accident with a kid who thought she could fly !! The break was just below the knee fortunately.... looking at her one morning I realised 1 leg appeared longer than the other ! The cast absorbed the damp from the atmosphere & was softening. stretching etc and gradually slipping down her leg.
If this happens to you, don't panic. By now the break will be stable but not mended. I would measure the other leg now in preparation... find a suitable lightweight splint to cover the area, Vet might even help here, cotton wool to pad, cotton wool bandage wrap (Softban), further bandage, follow by Vetwrap. You can then re splint without calling the Vet out.
It is always worth keeping a few various sizes of the lightweight shaped splints in your med. supplies.
Jalani does tend to charge around like a bull in a china shop when panicked.
Ring me any time.
