My Cat had her kittens 3 weeks ago and Mum and babies are doing well, but mummy is an out door cat and got fleas, she has passed them onto her babies. Is it safe to bathe them at this age? Also how soon can I have the Mum spayed? She is still nursing.
Thanks in advance:)

It's safe to bathe them, and I'm not sure about the other questions. I have four thee week old kittens and found out they had fleas.
If you bathe them, make sure to get them dry really fast. Use a hair dryer if you need to but put it on low and old it away from the kitten.

(I found that Lemon Joy soap will remove fleas.)
