Finally was able to print the brochure, but I had to use an old desktop computer.  My notebook won't download some things even though I tried to disable the pop-up blocker utilities.

Thanks for writing all that out.  There seems to be quite a difference between some of the requirements.

For example, calcium.

The NRC recommends .18g per day, but Dr. Strombeck's recommendation is quite different.

128mg/kg body weight = .128g x 4.5kg for a 10lb cat = .576 g

Did I do that right?  If so, why the large difference?

Frankly 5Cat, I don't know why there is some (maybe a lot) of difference in the tabulated daily requirements for cats.  Ths is speculation as of yet on my part, but I think the NRC requirements are MINIMUM figures; whereas others, like Strombeck's, reflects the IDEAL nutrient intake per weight of the animal.

Is that like for people: MDR (minimum daily requirement) and RDA (recommended daily requirement)?  Thanks so much for posting that info, Kaffe.

Oops got that wrong, recommended daily allowance.   Shocked

Kaffe and MrsP,

That makes sense.  Also, the NRC info was originally published in 1986, and was last reprinted in 1992.

So, is Dr. Strombeck our best source for this nutrient info?

Hi 5CatMom - not really one site, but I've compiled information from several sites.  I haven't really focused on the various vitamins/minerals because I feel the Wellness that they are getting should provide that.

Here are some other links that might be helpful:
Feline Nutrition - Dr Zoran: 
Dr Lisa Pierson:
Pet Education:

Happy Reading!

it's funny. i have always feed cats canned food. dry seemed so unappealing! i left it out for snacks, but they always got wet. i also rotated for variety. both wet food and rotating diets are now being recommended. i didn't learn about the water issue until i started raw a few years ago. i've always had decent drinkers. sometimes it's just finding out what they want to drink out of! lol!~ our childhood cat would drink out of a certain coffee cup on the bathroom counter. it's actually a good set up 'cause it's so easy to refresh the water throughout the day  Cheesy

What a wise pet parent you are.   Wish I had known a lot sooner about wet versus dry for cats.  Always gave them a treat of wet several times a week and the older ones got wet because they were more likely to eat it.  Just a few months of mostly wet now, and I see the difference.  I was always told not to give them too much wet, that it would upset their stomachs.  Wow, how wrong was that!   

Actually, some Vet Techs have been telling me that tooth decay is likely caused by an all Wet Diet.  Then they went on to their classes, training, etc (they either promote Science Diet or Royal Canin dry).  So, unfortunatley - must do own reaserch.
