Thankyou Growler and L4H!!
Teeka is doing better. They checked for ulcers - couldn't find anything. Tested for toxins, and found lead in both kittens - which leads them to believe that they most likely got into some kind of insecticide. :sad:
Thankfully they are sure both kittens will be fine, though Teeka will be going home with the Vet Tech so she can monitor her progress and continue syringe feeding her. I guess Teeka won't be released until she is at least eating wet food again on her own.
We'll miss her, but I'm just relieved that she will be okay!
