Knowledge etc aside, if the lady was rude to you and there is another vet in your area, I would recommend paying a visit to the new practice. I had a terrible time with my first vets and after they messed me around one too many times I switched and cannot believe how fantastic my new vets are.

Although everyone's first choice re: vets is always "can they help my pet", and rightly so - at the end of the day, a veterinary surgery is also a business and businesses revolve around good customer service. If they are rude and unhelpful (or like the guy on the phone, give you mostly wrong information), then they don't deserve your custom and your money.

Back on topic, I'm sorry that you were all geared up for kittens only to find that it was a phantom pregnancy or reabsorption, I'm sure you are disappointed! If you are planning on having a litter in the future then at least you will know the dates and know what to expect this time! But if you're looking for an tom cat to breed her with, make sure you check that the tom is free of any diseases or parasites (eg feline herpes virus or ear mites etc) that he might give to your cat. With pedigrees, stud owners have their cats regularly checked but with moggy boys that isn't usually the case.
