At what age do kittens start to pee and poo on their own?

Question

And what is the earliest they can get neutered?

Answer 1

They should be pee'n and poo'n immediately if they are eating. Call your vet to see when the earliest they will neuter the cat, some go by age, some by weight, but you definately want to get it done as early as possible to have the most loving and healthy kitty.

Answer 2

Pee and Poop - most likely within 1 week (pee might be earlier)

Neuter - after 4 to 5 months.
