Does your kitty have allergies...?
Or are you vegetarian
I ask because i'm vegetarian (ok I eat vegan 97% of the time,but I still call myself vegetarian because I do occasionally eat dairy,though I prefer organic dairy& i'd eat eggs (rarely) only if they are organic& gotten from birds kept ONLY as pets& fed organic food...you get the picture
...I try to be as vegan as possible...& by rarely I mean a few times a year)
That being said,I never altered any of my pets diets...because,to be honest,it never crossed my mind..but I'd be worried i'd be doing more harm than good.
Vegetarians (especially vegans) have to work a bit harder to get all their vitamins.
& My pets get really picky,really fast
I only ever fed vegetarian foods as a treat in the past.
They don't really go crazy over it as they do the alternative.<-refering to my pets.
That particular product I never tried,I'd really really research before you consider switching your kitty over though.
Unless your kitty has an allergy,then thats different& you can talk it over with your veterinarian.
Sorry I'm not of any help...
