Like myself, Rowan has owned a lot of cats. She is advising you that actually there is no real merit in letting your cat have kittens before they are spayed. Seling pedigree cats is also how some people make money and is their main source on income and there is a market for them, people doing it legitamately are also set up properly much like those who sell pedigree dogs, hence why Rowan suggested that unless this is what you plan to do, there really isn't much sense in your cat having kittens. She was not being pompus. So the suggestion is that when you take the cat to the vet and assuming she is not already pregnant or ill, then it would be a good idea to have your cat spayed.
