Techni-cal (a Canadian company) seems from its ingredient list when I
last looked to be similar to Science Diet (neither having on the face of
it very high quality ingredients).
Now, some animal "by-products" like kidney, liver and lung are very
nutritious when balanced out with actual "meat" but the problem generally
is one does not know the quality of the by-products even if they
supposedly conform with AAFCO specs which are very much a minimum, and
not a good minimum at all. The same thing goes for chicken meal which
when made of high quality ingredients is excellent and can also be of
Many people swear by Science Diet for example and it probably is OK but I
believe for the price they are getting they could just have easily used
far higher quality ingredients to get the same nutritional value and
still make a decent, although reduced, return. I understand that they are
not using ethoxyquin anymore and I really do not have such a major
problem with BHA and BHT as some do but propyl gallate causes me a bit of
a problem even though it is used as an anti-oxidant in oils, margarine
and meat products for human consumption.
Nutro (Natural Choice and Max Cat) is good quality and superior to the
others you listed. Whether it is necessary to go to super-premium I
cannot really say although psychologically *for myself* I prefer feeding
my cats Innova. I do think some of the ingredients in the super-premiums
are geared up far more for the cat owner (or guardian if you prefer) but
I do like the fact that the ingredients are all human grade.
In actual fact, my cats' diet is definitely superior to mine! :)
I know Eukanuba food a it is supposed to be good (as well as Iams).
Anyway I can recommend you trying Hills food. (I hope it is available at
place.) One of my cats would not eat anything else but Hills and she is
healthy and beautiful. Hills has the right combination of minerals to
prevent kidney failrule.
