Hello!I want to ask a question. 1)My kitten is 6 months and it's a girl.And I want to sterilize my cat .So...what's the better sterilization or castration.And I wanna sterilize it in 10 or 12 months.Can we sterilize it before the first estrus? 2) We vaccinated Tiffany twice. It was Nobivac Tricat Trio .So at first we vaccinated it the 21 of February,and the second at 13 of March.And we will do rabies vaccine at 3 of April.And can we do chlamidia vaccine on September? Sorry for my English:)

Great questions! I will answer the one by one for you :-)

1. Female cats are spayed, so that is the only option for you to do for Tiffany. I would have her spayed as soon as possible, as you do want it done before she goes into heat the first time. Cats can go into heat as early as six months of age, so it's best to get it done now.

2. Good on you for vaccinating her! I would get the chlamydia vaccine as soon as possible for her as it's highly contagious. You can do it as soon as two weeks after the rabies vaccine. It's best to space out two different vaccines at least two weeks apart for the best immune response.

Your English was great, I hope this helps!
