Just wanted to post a symptom update - I'm here for the next 24 hours or so, just came home to take care of my boys. =) I need to do some research on HED, too.
We've just about concluded that the early warning signal of what is going on now was several falls - from the couch and end table, just looking over the edge like normal and THUMP hitting the floor. He's a lot more inclined to do it now, he fell off the bed last night when I glanced away.
His balance is almost non-existent, he used to stay crouched on his hind paws to groom his entire back and belly, and to do so now without falling over backwards almost immediately requires a hand behind him. Add to this the fact that he HAS finally started developing penis plugs - I got one out last night and he had already redeveloped it 12 hours later this morning. :doh:
Jacob is using his teeth instead of his tongue. For eating yogurt off a plate, for getting water off my hand, and in comparison to his previously almost constant kisses to any part of people he could reach, nibbling at my lips/face instead of kissing. He has an occasional upper lip snarl on his left side, and his teeth appear to have become slightly angled to the right - they are grinding just a little crooked. Cause, or effect?
His leg muscles are incredibly weak. I do need to do some research on HED, now, but this doesn't seem to be localized to his back legs. All legs and toes are having trouble gripping, he just sort of slides off your leg/tummy onto the bed/couch, and more often than not lands on his head/side rather than his feet.
He is still, as David said, poofed, squinty, sleeping more than is normal even for a boy rat of 18 months, not wanting to explore or play except in a confused, wandering sort of way, and incapable of climbing. We started him on Prednizone last night, and still have Baytril for another day or so. No real improvement yet, but hopefully he will at least get a little more appetite. *crosses fingers*
Any other thoughts, based on this? We were wondering if it was possible he has had a stroke...
