Castor Oil harmful?

My budgie (Chocolate) is going to the vet tomorrow in the afternoon. She seems to be sick. SHe's really poofed up. Something stumped me though. She's chubby. Very chubby. She also eats a lot. This is weird because when budgies are sick they usually lose weight and eat less. She threw twice though. Is she constipated. Should I give her Castor oil? Will this help or should I just hold off now?

I'm not sure actually feeding them any oil would be good. There is an oil that's used for emergencies & it's only cod liver oil (hat I know of), no other & I also don't remember what it's for. If you're concerned about constipation figs, grapes & lettuce will help better, however, if it isn't cinstipation & she ends up with diarreaoh you may cause her to become more ill & have dehydration which may end up being worse too. If you really want to take her in now, I'm sure your vet will accept an emergency.

We already have an apointment. It's not an emergancy yet (thank goodness). I just wanted to know if there was anything I could do to make her feel better. Well she's sleeping now. Thank you Kim
