Help Henrietta's Emergency Recovery

Henrietta is an almost nine year old dilute calico rescue who is normally the biggest cuddler. A few days ago she began vomiting and was not able to keep any food down, and eventually stopped eating and drinking entirely. We don't know what triggered this episode, but don't believe it to be environmental since the other cats in the household are still healthy and happy.

Through two vet visits (one normal and one emergency stay), she has begun to eat and drink again and can hopefully stabilize soon. But due to some financial hardship, we are having trouble paying these vet bills without taking on a lot of debt.

Any help you can give will go a long way, especially if she has another episode and we need to pursue more aggressive treatments.
