I pay around $40 – $60 for just a check-up or follow up. $100 bucks is a bit expensive. But from the sounds of it you may want to look around for another vet. You may not need one now, but you could take the time now to put some vets through the screening process. Better to have a rabbit savvy vet if an emergency pops up. Did I already give you the link to the screening questions? If not, let me know and I’ll post the link.
Regarding the yogurt drops – I have always been informed by house rabbit experts and rabbit savvy vets to stay away from yogurt drops. They are high in sugar and can contribute to an overgrowth of bacteria which could lead to serious digestive issues. Ironically, though it has been used to help with an imbalance of bacteria this is what the House Rabbit Society has to say about that particular aspect:
“Yogurt with live cultures has been used as a source of acidophilus and has been used in baby formulas. Adult rabbits do not produce lactase, the enzyme which digests lactose sugars (milk) and I advise against using yogurt as a source of acidophilus, if one chooses to supply it. Because a weanling rabbit’s gut is changing so drastically, it would be realistically impossible to determine at what exact moment a weanling rabbit develops intolerance for dairy products. Freeze-dried, organic acidophilus cultures are available at better health food stores and would probably be a better, safer choice than yogurt, in my opinion.” SOURCE: http://www.rabbit.org/care/babies.html
Even pineapple and papaya have been in debate regarding whether they REALLY help, but they don’t hurt in the recommended dose so many of us use them for digestive support.
Bottomline for fiber – stay away from sugar as a fiber supplement, and just stick with hay hay hay. Alfalfa hay for babies and young bunnies up to a year is norm.
Regarding feeding him alfalfa for a whole year. Usually somewhere between 7 months to a year is when you would begin weaning him off alfalfa hay and pellets, and introducing timothy hay http://saveabunny.com/?q=diet
And gravehearted is right – bunnies don’t get hairballs in the sense that a clump or ball of hair causes GI stasis. Usually a blockage is caused by a poor digestive system due to diet, illness or some other issue. Those issues are what can cause a the tract to slow down or stop and many people then say it’s due to hairball because the digestive tract was not able to pass the hair through. That’s why I double triple ditto Gravehearted’s advice lots of hay, fresh water, and brushing (especially during a molting!)
And stay away from high fat, sugary treats. Even healthy treats such as fresh fruit should be given to adults in small amounts (1 – 2 oz a day)
