Blu should be getting a high quality cat food during her pregnancy, which will provide her with all the vitamins she and her kittens need to be healthy. It's typically not recommend to give a cat a vitamin supplement during pregnancy. That's because an overdose of vitamins can cause ill effects in Blu and her kittens. Too much vitamin A, for example, lead to the develop of cleft palates in the kittens. You can speak to your vet to see if they think it's safe to give her a vitamin supplement, and they can recommend one. Leave food out for her all the time, and you can supplement her diet with canned cat food. Make sure she always has access to plenty of fresh water. Get her up to date on her deworming treatments, and make sure she is flea treated. It's safe to use Revolution on pregnant cats. I would have her brother neutered to prevent him from mating with her again.

    Pets don't require vitamins if they are on a high quality pet food. Also unless your cat Nancy was diagnosed with a vitamin deficiency, she doesn't need vitamins at all really. Vitamins in people, in fact, are designed to replace the nutrients that we are missing from our diet due to poor food choices. The only recommendation for feeding a pregnant cat is to feed them a high calorie diet, which is why we recommend kitten food for the 2nd trimester on until the puppies are weaned off of mama cats milk. I hope that this helps and best wishes with your mama cat Nancy and her soon to be kittens! You sure sound like you are preparing well for the big day! : ) Take care.
