Why does my 1yr old female kitty hisses at our recently acquire 11 week male kitten?

Wow, a lot of inaccurate answers... males typically reach sexual maturity (ie are able to get a female pregnant) around 3-4 months; females around 4-5 months. With larger breeds, it's sometimes a little later. It *is* possible for them to be early bloomers and become sexually mature as early as 10-12 weeks.

There's a good chance your male rabbit hasn't reached sexual maturity yet... however, it IS possible that he has, therefore keeping them together at his age is risky. Most vets are willing to neuter males as soon as their testicles descend (keep in mind, they *can* kind of suck them back up into their body when you go looking for them), but neutering isn't a sure-fire fix when it's first done - males can remain fertile for up to 6-8 weeks after neutering! Your best bet to prevent pregnancy, if separating them isn't an option just yet, is to get your two females spayed - females NEED to be spayed anyway, as unspayed females live, on average, only HALF as long as spayed females because they're so prone to cancers of the reproductive system.

It's also not safe to keep two unfixed sexually mature rabbits together even if they're the same gender, as hormones can provoke vicious or even deadly fights. If you're looking for a way to make multiple spay surgeries more affordable, your best bet is to contact shelters that take in rabbits and rabbit sanctuaries/rescues and see if they can recommend any good vets that do low-cost spay/neuter surgeries or have low-cost spay/neuter clinics that accept rabbits (many only do cats/dogs). If you have any more bunny questions or just want to chat/share stories and pics, I highly recommend http://rabbitsonline.net - it's an excellent community; very friendly, active and helpful!

They don't mature till at least 3 months males usually won't be able to get a female pregnant till 6 to 9 months.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
