There are several folks here that are extremely knowledgable and experienced when it comes to cats. With the possible exception of a good vet this is the BEST advice you'll ever find!!! Your mommy cat to be needs veterinary attention NOW! Find out from your vet about her nutrition needs while she's pregnant, how to keep her healthy and comfortable, and most important...what to look for, what to do, and when to call the vet for help. While there, arrange for a spay and neuter ASAP. If money is a problem, look into your options.
