Okay, so I looked back - I had messaged someone on the 30th of May, and it was almost 2 weeks then.....so about 5 weeks. In that time went from fighting trying to take on older/dominant Roo ( and winning sometimes.) To hurting his leg and not standing (I thought because of pain)in a 48 hour time span....brought him in, and in 5 weeks went from shaking legs standing (again, thought it was pain, treated wounds and gave him ibuprofen for pain), to couldn't stand, but could still move lower legs & had weak grip in feet....to no use of legs now...no resistance at all during exercises, not a glimmer of grip with feet.
If anyone thinks it is something else, feel free to offer suggestions for treatment. But the poor guy just can't live like this and I have no idea what else I can do for him.
