kati is almost 14 and this happens on and off some weeks it seems to be more times than others...they are like little shakes or shivers...however when she was 3 she took a slow fall as a lounge chair tipped over and she landed on the deck..she had the breath knocked out of her and i am wondering if this could be the reason for her little episodes..also in the past 6 or so years she has had a true seizure where she just got rigid for a minute or so. this has only happened 3 or 4 times... the vet has her on 1/4 tab of phenabarbitol every night and i don't see any great changes..is this drug going to do any additional harm to such a little girl 5lbs? please give me some support on this awful situation... can't lose her..just lost scarlett and rhett last year from kidney failure.
