Can kittens be born with fleas and worms?

In short, kittens cannot be born with fleas but they can get them from their bedding or their mother very quickly. For me this means that anyone who's involved in breeding their cat (which should not happen by the way unless they are a breeder registered with a cat association) needs to ensure that the queen's nest is spotless in terms of fleas. No fleas in the mother's den would seem to be common sense. Or on the mother. And around the home generally.

I am sure though that in homes where cats are breeding informally there are piles of fleas because the owner is behaving irresponsibly. I can visual that scenario quite easily. Many kittens will have a flea infestation at an early age and it will be a treat to their life.

Resistance to fleas is age related: old and young are more vulnerable. They have less resistance and they will be debilitated and some will probably die.

Worms

Neither can kittens be born with worms but they can be infected through nursing so if the mother has worms so will her kittens.

Once again this points to the standard of caregiving in taking proactive steps before the queen becomes pregnant. Is she in good health? And worm-free?

The problem with kittens being infected with worms is the same as stated for fleas above. How good are the proactive steps in preventing both endoparasites (worms) and ectoparasites (fleas) taking up residence in and on kittens before the mother becomes pregnant?

It is pretty obvious that in most non-cat breeder homes proactive steps are rarely taken. Kittens will have a tough start to life and some will die.
