what is the difference between a girl and boy kitten

I am thinking of adopting a kitten - i just lost my baby of ten yrs.. genie and i though of getting a new kitten. i just dont know if i want a girl or a boy. i have two older kids and two ferrets. will they get along as well? i need advise..

There are things to consider when choosing the sex of an adoptee kitten such as are there any other cats in the house? Male cats will often fight if both are not neutered or have not been neutered long enough before being introduced. Male and females often get along very well together as long as the threat of the female beoming pregnant is adressed (spay & neuter if kittens are not desired). Female cats, if confined (indoor cats), will often fight until the other leaves or is dead whether they are spayed or not.

Also, male cats are prone to urethral blockage, often resulting from crystal formation in the urine. When this occurs, the cat will not be able to urinate and his bladder will fill and the toxins in his blood will begin to collect and build until he is seen by the vet or dies. Signs will not always be apparent unless they are being watched over. This is not to scare you, as urethral blockage is not common, but it does affect a small percentage of male cats. Blockage is virtually unheard of in female cats. Chronic blockage in male cats can be solved by a "PU" surgery where the penis, along with much of the urethra, is removed and the risk of blockage is decreased drastically. Un-neutered (intact) male cats will often "spray" urine on walls, furniture, etc. in a territorial-marking behavior. Intact males are also at higher risk of contracting testicular cancer (obviously).
