Disclaimer: I am neither a vet nor an expert. I’m an experienced bunny mom surrounded by many extremely knowledgeable bunny people. Nothing on this list should be used as a stand-in for high-quality veterinary care.
Most of these items (in no particular order, by the way) are useful for bunnies in the same way that, say, rubbing alcohol and Band-Aids are useful for humans: It’s a good idea to have them on hand for immediate care or relief, but you might have to go to the doctor anyway.
1) Simethicone – Yep, the same stuff you use for a gassy (human) baby can provide relief to a gassy bunny. Gas in bunnies can be deadly, and not in an omg-who-farted way. If gas builds up, simethicone can help get rid of it and get things going again. Follow the directions on the bottle for dosing.
2) Thermometer – with a flexible tip. If your bunny stops eating, drinking, or pooping — or just seems to be acting “off” – gastrointestinal (GI) stasis (see #1) may be to blame, causing your bun’s temperature to drop. Normal bunny temp falls between 101° and 103° F; bunnies in stasis will have a temperature below normal. Bunnies fighting an infection will have a temperature above normal (more on this in a minute). Note: Bunny temp is always taken rectally.
3) Critical Care – In whatever flavor you think your bunny would prefer, though in general you can’t go wrong with apple-banana.
4) Assorted syringes – Your vet will always give you one or two to go with whatever medication your bunny has been prescribed, but it’s a good idea to keep lots of different sizes on hand. Critical Care, for example, requires quite a large syringe, while most oral antibiotics require a pretty small (one-mL) one.
5) Baytril (or Bicillin) – These are bunny antibiotics that usually cannot be obtained without your vet first examining your bunny. (For what it’s worth, I’m a Baytril girl myself. The bunnies love the taste – usually peanut butter or banana.)
6) Metacam – This is used as a painkiller for bunnies and very often in addition to an antibiotics. It doesn’t have the 90-day expiration date that antibiotics often do, so it’s easier to keep on hand long-term.
7) Zymox – the Holy Grail of ear medication for bunnies. I can’t tell you how much I love this stuff. If your bunny suffers from wax overproduction or any sort of ear infection, get some today.
8) Styptic powder – At some point, you will clip your bunny’s nail too short and it will bleed. Styptic powder will help stop the bleeding. Unfortunately, you will never forget how horrible you felt that one time it was your fault your bunny’s poor little toe bled.
9) Vaseline – Always coat the thermometer tip with Vaseline (or KY Jelly, or even olive oil, in a pinch) before taking your bunny’s temperature. Lubrication will help you avoid causing pain or discomfort.
10) Probiotic powder/paste – There are a few to choose from, but among my fellow bunny moms, Probios seems to be the most popular. It’s normally used for bunnies with chronic GI issues, but can also be administered to a bun in a bout of severe stasis (i.e., with an otherwise healthy gut).
