This has molasses in it it says. Bunny’s aren’t supposed to have molasses as it’s to high in sugar and is hard to digest. Are these still ok? Also would they be ok for a 10 week old Holland lop.
Answer by • Apr 05, 2021
Cane molasses is included in small amounts in most of Oxbow's Natural Science supplements to act as a natural binding agent to help hold the high fiber, plant-based ingredients together, providing a uniform source of nutrition to your pet. Plant-based cane molasses is an unrefined carbohydrate, meaning it is absorbed much slower over time when compared to rapidly-absorbed, refined carbohydrates. This prevents sudden spikes in blood sugar that are often noted with the consumption of simple carbohydrates.
Does this product aid in hair ball prevention in rabbits? If not, what product will?
Answer by • Jun 08, 2021
There are no ingredients specific to the prevention of hairballs but it will certainly keep hair moving through the system. Rabbits are unable to vomit, so they do not have hairballs like cats. Feeding a high fiber will assist in preventing blockages, they suggest hay-based pellets as well as a large variety of hays for bunnies.
