Raw Meat May Not be Enough for Your Cat

     Recently a study was completed at a zoo in Illinois regarding the raw meat diet. It covered at least 225 large felids who were fed diets of raw beef, bison, elk, and horse. Care was taken to ensure the meat was as fresh as possible, though the meats were trimmed for the cats.
     It can be inferred that our house cats have the same nutritional needs as the larger cats.
     It was found that though the meats were digested readily, the nutritional needs of the cats were not completely met, and the cats were lacking in essential fatty acids. The elk diet was lacking in overall fats.
     I'm not about to travel to harvest some bison for my cat, so I've sent an email to the person in charge of the study, which overall, I thought was done well. The sample size was adequate to draw the conclusions presented (unlike some medical studies!) This study would be much more useful/practical if it focused on readily-available local meat sources.

My email:

How well did the cats (large or small) do on a diet of rabbit, guinea pig, mice, and small game birds like quail and pigeon?

I only ask because that kind of dish is much more likely to be what most people are going to want to feed their pet cats were cat food prices to increase.

What kind of natural source would you recommend for the missing essential acids? Maybe grasshoppers, eggs, fish, or Black Soldier Fly Larvae? 

Kelly's response:

Chrissy – good questions. We have not tested any of those ingredients in cats because our main focus has been on large captive exotic cats.  To apply more data to small captive exotics and domestic cats, we recently performed a study in which many smaller prey items, including rabbits, mice, rats, quail, and chicks, were analyzed for nutrient composition (protein, fat, etc.).  These data have not been published yet.  We have not tested the digestibility of those items in domestic or exotic cats though.

 As for fatty acid content, the main problem in our study was that trimmed meats had very little fat of any kind.  As long as fat is not trimmed off, numerous sources could be used.  This probably would not be an issue with whole prey items.  Those items, however, often have other problems (e.g., mineral deficiencies).  That data will be submitted for publication soon. 

     So... lesson learned, never trim the fat off of your lion's elk dinner!

     This nutrition label is straight from Purina's website, and they are arguably the largest producer of rabbit feed in the United States. It is known that animal food companies will buy the cheapest ingredients, regardless of source, that meets their standard of nutrition. This means that one day you could be buying pellets made of mostly alfalfa, and another day you could be buying pellets made of soybean. 

     In 1982, the Peace Corps published a pamphlet about rabbit nutrition, breaking it down simply by the type of rabbit (pregnant, resting, lactating) with nutrition profile that rabbit needs. Like people, rabbits need protein, fiber, carbohydrates, minerals, and vitamins. 
     If you were to use this to formulate your own feed, you would need to adjust the amounts for the size of your rabbits. Normally this would be measured by weight, and one kilogram is approximately 2.2 pounds.
     Overall, protein seems to be the largest limiting factor for rabbit production, as most of the minerals and fiber can come from the addition of a good quality hay. Some plant proteins are readily absorbed by the animal's digestion, others are not, and this needs to be taken into account when mixing a feed.

Rant: Don't Read If You're Faint of Heart

     I don't usually have personal drama because after knowing what nutjobs most people are I limit my interaction with strangers in my personal life, outside of work and school that is. And am happier for it.
     But today, I noticed that all four of the hubcaps are missing off my car. They were there about two weeks ago when my dad helped me top up the tire pressure. Since I hate driving, I have maybe driven only twice since then. I quickly secured up the locks on the rabbits in the backyard.
     I don't understand why I am such a target. Is it because I live alone? Are my neighbors jealous because I have central air? Is it all crazy exes that I've dumped because they haven't treated me well? I did swear off former military guys and firefighters because they are all crazy and treat women like shit. I don't feel like I am beautiful or smart enough to make another woman so jealous as to do something like this, but anything is possible. I have a big mouth, maybe I upset someone? Maybe someone hates paramedical practitioners? I'm not working at the moment. Are people jealous of my amazing garden? How can they see it beneath all that grass?
     I seriously doubt someone stole them for their own use. My tires are ridiculously small and flimsy, they have to be special ordered from the tire store because they sams and walmart don't carry them. The hubcaps, are, of course, correspondingly tiny.
    I was just teased about the new clothesline, that someone might come up and steal my laundry from my carport. I laughed it off. Sure, that person should probably be the first one I suspect, but he would have nothing to gain from vandalizing me.
     So, WTF? FML.
