Here is the link to the last thread I'd posted on...
Basically one of two feral kittens we were bottle feeding was suddenly near death a few weeks ago... getting close to 5 weeks old, the little boy was apparently blind from the excess cranial pressure and having displaying lots of other neuro injury symptoms... constantly flicking tail, etc. How he got hurt is still a mystery. He was usually with a smaller sibling and they were rarely out of site from my wife.
As covered in the linked thread, we had him treated at a emergency vets office over a weekend, and MANNITOL did a great job of reducing the pressure causing all the problems... He seemed all better. But then, just over 2 days later he started sliding downhill quickly... another dose of Mannitol and like magic, he seemed fine again. This time he was also put on prednisone (sp?) and a full week later we are now stepping down his steriod dose.
So far everything seems totally normal.
We are hoping of course that the problem was actually caused by a physical trauma and he has had time to 'repair' the damage. Hopefully it's not a congenital problem that the mannitol 'fixed', and the prednisone is able to keep down for the time being. A lifetime of prednisone isn't an option for a 6 week old kitten.
We still have our fingers crossed, but from our experience, the IV drug Mannitol is a utter lifesaver for a cat/kitten/pet that is suffering from a severe concussion. It's diuretic effect works alarmingly fast. I mean the first dose literally revived a limp nearly lifeless cat back into a wound up kitten in less than 4 hours.
