Latest update on Yoda's recovery!

Well, we finally got conclusive results back from the vet on what the cause of Yoda's bone disintegration was. They were unable to determine whether it was cancer or infection based on the X-rays, but were fairly confident it was cancer for various reasons I won't get into.

Well, they were wrong. He had osteomyelitis. The vet said that based on lab results it had existed for quite some time and the damage was extensive. He said that it was highly unlikely they'd have been able to save the leg in any case. Well, it's done now and the good news is that he doesn't have the pain from the bone infection and he is not a recovering cancer patient, so it's not going to show up elsewhere in his body.

Aside from the histology, we are all getting used to a new normal. Yoda is moving around, eating, etc. The biggest challenge now is addressing his boredom. He LOVES the outdoors and I think he is likely a little depressed that he can't go outside. In fact, he DID escape earlier this week at nighttime when someone unexpectedly knocked on our door. I was a wreck for the 2 hours until his return (unscathed).

One question: I've noticed a bit of strange behaviour from him. Last night he was grooming and then suddenly started biting at his tail and made a very strange noise unlike his normal mewing. When I touched his tail, he jumped and looked distressed. He's made the same strange noise two times since then ...i wasn't watching him when he made the noises, so not sure if it was related to a physical pain, but it has me worried. During this whole ordeal and his previous eyei injury, he suffered through his pain in silence, so these weird noises are concerning. Is it normal for cats recovering from amputation to have sudden pains?  

Thanks again for your guidance and support, it means the world to me!
