Pet's info: Cat | Siamese | Female | unspayed

My 4 month kitten seems to have all the signs of being in heat. She's is very restless and rolls around the floor in a wierd way and keeps licking herself. She seems really miserable. When can I get her fixed and until then is there something I can do to help her? And how long will she be in heat?

4 months of age is very young for a cat to be in heat but she certainly could be, especially since she is a Siamese. If you have any concern that there could be another reason for her behavior than have your vet take a look at her. If she is in heat than it will last on average about 7 days and she may go back into heat 1-3 weeks later. She is old enough to be spayed so talk to your vet about the best time to have her spayed. There really isn't much you can do to help her, just make sure she doesn't get outside or around any male cats.

    This is very young for her to come into heat, but not unheard of. They can go into heat as early as four months. She is not too young to be spayed, but we prefer not to spay them while they are in heat. This is because the tissues tend to swell and increase the possibility of complications. You can schedule a wellness check at anytime though. The Vet will want to do this prior to spaying to ensure she is healthy for the procedure. They can then advise you on the best time to get her spayed and get that scheduled. I hope that helps and all is well with nala.

    Hello there! Cats are seasonal breeders. They typically start going in to heat in the warmer months (spring and summer). They will continue to go into heat repeatedly until they are bred and pregnant. This can last several months until the seasons change the weather gets cooler again. There is not anything you can do to prevent her from going in to heat other than to spay her. If you do not wish to have her have kittens you should keep her inside AT ALL times and away from any male cats. So if you have another intact male cat she will need to be isolated away from him too. A male cat will be able to smell her phermones and will seek her out to breed her and this can happen quickly. So take precautions unless you want to have kittens. I hope this information has been helpful to you. I wish you and Milo all the best!

    Great questions! At four months old, Oreo is old enough to be spayed, and I highly recommend getting it done. Even though she doesn't go outdoors, having her spayed will have significant health benefit for her. It prevents her from developing mammary tumors, 90% of which are malignant in cats. It also prevents her from developing a pyometra, which is a life threatening infection of the uterus that requires spaying her to treat along with antibiotics. It also helps you avoid the very annoying behaviors that accompany a cat when they are heat. They are VERY vocal, demanding of attention, and cry all hours of the night. Trust me when I say you don't want to deal with this behavior, as cats cycle frequently certain times of the year, and it's a problem you will have to deal with on a regular basis. I would call the vet on Monday to set up an appointment to get her spayed. Good on you for wanting to do it :-)

    Yes, I recommend to call you vet and discuss having her spayed. The veterinarian may try to get her scheduled in between cycles but cats tend to come into heat so this may be difficult. The doctor will determine the timing of the procedure but cats can be spayed while in heat. Keep her strictly inside and be careful because she may try to escape. I hope this helps.
