Yes, bless you for rescuing her!

Syringing water into her mouth is a very good idea for now. And so is giving her some pumpkin to see if that helps get her to poop. That's a serious situation if she doesn't. Please keep the vets updated as you go along. Let them know tomorrow how she's doing, especially if she is still having trouble. Maybe they'll have other ideas and suggestions or want to see her again sooner than scheduled.

Thank you so much for all you are doing for this precious creature! My cat Sparkler and I are sending you and her loads of loving good wishes and hopes and prayers and healing energies. Please keep us posted!
