I'm sorry for not updating sooner! We're having fuuuuuun times up in here.
I was able to get an advance on my paycheque, and took Kraz in to see the vet as soon as possible, which unfortunately wasn't until Wednesday morning (I'm ineligible for any sort of care credit since I'm young and have a credit score of zilch).
Sadly, we're all kinds of baffled. The vet found a laceration in the back of Kraz's ankle, but it seemed very old and wasn't bleeding or sore. Kraz still has circulation in his foot, and tests have ruled out tumours, deficiencies, toxicity poisoning, viral disease, and nerve damage.
Basically we're boggled.
For the time being Kraz is on medications to make sure he isn't in pain, and I'm continually modifying his cage to make it more accessible for him with one foot.
I made a joke a while ago about how all my pets and I keep hurting our feet. I think we have a foot curse.
