Vitamin C

Just wondering how many of you mix Vitamin C in your cat's drinking water? Ever since I had 2 of my babies fallen sick last year, the vet told me to put 2 ml. of Vitamin C in their water. I stopped for a while when the 2 recovered but restarted few weeks ago when Ni started sniffling. No more sniffles after 2 days. Still, should I stop again? I read that cats do not need Vit. C.

the ave healthy cat may not need extra C but it seems your might ... I would suggest some blood work

Thanks! You may be right. Ni is anemic so he is the one who may need Vit. C once in a while.
