Your bunny most likely has Gi-stasis. It is fatal if left untreated. There are several things you can do to get her through the night though. Please do all these things if possible. Here is a link on Gi-stasis:

- Get the rabbit to a vet. Your rabbit has a high chance of dying if it is not taken to the vet. I cannot emphasis on how much this rabbit needs to go to the vet.
- Give her infant gas drops:

You can give her 1ml by mouth every hour for the first 3 hours, and then 1ml every 8 hours. If you don't have gas drops you will need to buy some or you can brew fennel seeds, peppermint tea, or chamomile tea in hot water and syringe feed it to your rabbit after it is cooled. NO HONEY. Syringe it to your rabbit every hour. These should help get gas out. It is a substitute for Infant Gas Drops.
- Give tummy massages. Massages help get gas bubbles out. Here is a link on how to do it properly:

- Make your rabbit run around. It may be that you must push her around and make her mad in order to get her moving, but it will be worth it. Moving around will get her gut moving.
- Give fresh pineapple juice. It can help with dissolving hair in the intestines which could be clogging her up. If you don’t have fresh pineapple you can use canned pineapple, but it does not work as well.
- Syringe feed Critical Care 6 times a day. If you don’t have Critical Care you need to soak pellets in water until they are mushy. Then smash them in the water until you have a mixture the consistency of pancake batter.
- Cut Timothy Hay with scissors until the hay has turned to powder. It will be very long hard work, but it will be worth it in the end. Mix it with water until it is also the consistency of pancake mixture, and syringe feed it to your rabbit when you syringe feed it the pellet mixture.
- Syringe water 6 times a day. Fill a bowl with water so that the rabbit can drink freely. Add some apple juice or pineapple juice to make it more appealing.
- Give fresh veggies (Romaine lettuce, cilantro, parsley, and kale). Soak them in water for a minute and feed them to your rabbit while wet that way your rabbit gets water. You can crush some pellets and put the pellet powder on the wet veggies.
- Order Critical Care and Infant Gas drops so that you can have them ASAP. Here are the links:
