Shelter staff discovered a 5-day-old orphaned kitten with a birth defect that left him unable to walk.

Knowing they were his only hope, they were determined to get this sweet boy back on his feet

An Orphaned Angel 

Most shelter staff are used to taking on tough cases and doing whatever it takes to rehabilitate animals.

So when a tiny infant kitten arrived on the doorstep of the Arizona Humane Society (AHS), they were prepared.

Zion was only five days old, orphaned with the rest of his litter and completely dependent on caretakers.

In addition to needing round-the-clock care in AHS' Bottle Baby Kitten ICU to survive without his mother, he was badly knuckling on his back feet and unable to use his legs normally.
