I believe he will get plenty of the vitamins with the Brown’s Jr’s and veggies. I did try this stuff you are talking about a long time ago and I always wondered if it altered the taste of the water and maybe would keep my rabbit from drinking as much water as they needed. I think if you think Finn might need extra vitamins you should discuss it with the vet if at a later date he might need it. I think now he is in a healthy and stress free environment too and I think that counts for alot.

I wouldn’t use the Bi-Odor internal water and urine deodorizer – to tell the truth I don’t know what’s in it, but I don’t like the way it sounds, it doesn’t sound like something I would put in my own body. You can control the odor more safely with the right litter and once Finn is altered that will help the odor as well in my opinion.

I’ve heard people post online about the bi-odor, but also would be cautious about it.
Although it says vet recommended – think of all the junk they tell us is recommended for humans – ha ha!

I used the vitamins on Nel when she was younger, and she actually seemed to enjoy the taste of her water with the vitamin drops added. She’s grown quite healthy, and I’ve since ceased using them. They’re probably not necessary but might make a decent immune booster if you’re dealing with a sickly rabbit. Otherwise if you’re feeding your bunny a diet of quality pellets, hay and fresh leafy veggies it’s probably getting all the vitamins it needs.

Now I just wish I could manage my own diet half as well as I do that of my bunny. heheheh.

Rabbits generally do not need an additional vitamin supplement and to get them back on track, feed a balanced diet and lots of love.  Rabbits get their vitamins from their cecal droppings and so I would think it would interfere with it.  I would talk to a vet about it further and I would not even bother with keeping them on hand or administering them. Here is an article on cecotropes:

As for the Bio-Odor, I saw a rabbit once that was on it and it didn’t look too healthy and the fur was real dry.  I would hesitate to use something that is only for the purpose of reducing odor.  The Aspen Supreme works great in the litterbox. 

I ditto what everyone has said. I do have personal experience with odor reducing type products. A long time ago before I knew much about bunnies, I was interested in that too. I asked a rabbit savvy vet about it, and she had said that though it may not directly harm your bunny, some bunnies will drink less water because of the taste of it, and that is not good, so to watch the water intake. My bunny did not want to drink the water at all. I noticed that right away, and so I stopped using it. Then, after he was neutered, the smell of his urine became much less pungent, so it wouldn’t have been needed in the first place.

I also second the Aspen Supreme. I mix it with Yesterday’s News as I don’t like too strong of a woodsy smell, but seriously, it really seems to take care of the odor – not just mask it.
