Is alkalive ph booster safe for cats?

If your cat is sick and dehydrated I would use pedialyte. I have used this for sick cats and ferrets. However, depending on how sick your cat is... if he is not drinking on his own you want to get him to a vet.. he will need IV fluids. Trying to force fluids down a cat is risky business.. he can easily aspirate the fluid and then die of pneumonia.
