my sasha had fits since she was 2, the vets never did say why but when she became ill with heart failure aged 12 her fits were a lot worse and i think she had always had a heart problem which caused the fits.
how long have you had her?
if this is the only one she has had i would say its was prob due to over heating, if she has more get the vets to check everything out including tests on her heart.
good luck with your little one
