Interesting articles that actually show how the subject of kale, calcium, oxolates and sludge are still in controversy.
The first article is more measured and explains that "
there are a few things you need to know before you begin giving your furry friends this kale every day," and then goes on to note that the oxalic acid in kale is "
associated with “tingling of the skin, and the mouth, " and that "
Secondly, there are chances this veggie can cause stomach upsets and other digestive problems. This is not a problem of only kale but several other veggies. Your bunnies may suffer from diarrhea, bloating, constipation, gas among other issues. " It also states that these "
oxalates can increase the chances of having kidney stones and reduce mineral absorption if the binding occurs in the gut ." It also suggests offering a variety of greens and to "
try to reduce the number of those that have high oxalic content."
The second article is an editorial and takes more liberties stating, "
Most people often wrongfully implicate kale saying it is high in oxalic acid (oxalates) and recommend that bunnies have sparingly " Then they misrepresent the House Rabbit Society, claiming it "
shares similar sentiments on oxalate levels." This is actually what HRS states: "
Please note that there is currently dispute within the scientific community regarding the levels of oxalates and goitrogens in kale. Many of our rescuers have fed kale daily, combined with other veggies, with no ill effects. Others have found that kale fed in large amounts on a daily basis may contribute to bladder sludge and other health issues. HRS encourages you to make your own decisions on how you feed kale to your rabbit based on this information, and when solid, undisputed research is found we will update this and other articles relating to feeding kale."
I think the key to take away from this is that variety is recommended. Kale's level of oxalates is in dispute, yet it is still rather high in calcium. So feeding it a couple times per week (or less) would seem more prudent than feeding it daily.
By feeding a variety of greens, rather than just one type in large quantities, there is less possibility of over-dosing on calcium or oxalates.
