rc is very popular, alot of cats eating it worldwide.
they can make the food smell very attractive to cats.
if you can afford, of cos can con't to feed rc.
kidney issue, BUN high, vet will recomn less protein, hence the less 'can food'. U can choose the rc for °kidney' , renal type.
RC's speciality is in these, food with way less protein-renal.
Huge kibble type to clean teeth, etc etc.
All these, is not available frm other expensive brands.
Science Diet is another one, but sd is loosing out to rc in the cat department.
You can formulate your own, 'can food° add low carb cooked food etc.
my personal gripe is rc way too expensive..
She's currently eating the hair and skin RC, but I bought the repacked one so its cheaper. Repack one still has very strong smell. Will run out soon even mixing with Pro diet because she really eats a lot, I guess because of nursing kittens. Maybe she doesn't need the special for kidney one urgently as yet, because it's for kidney disease cats and she hasn't reach that level. Will try to look at the other suitable foods as well. Sometimes we give her leftover meat from our cooking prep as well. Thanks for advices.
