Is Milly 'Calling' ?

Hi everyone,
Milly is behaving strangley every two weeks or so. She talks [which is really unusual] and is very cuddly and wants groomed and stroked all the time. This lasts for a few days, then she reverts to her old self. She is six months old and this has been going on the a good few weeks. I think she is calling and I am planning to have her spayed soon. She is an indoor cat and althoough she goes to the door, makes no attempt to go out. This time when she is calling she has stopped eating [she has not eaten for two days] Is this normal? or is there something wrong. Her sleep pattern has also changed [she used to sleep overnight], at the moment she keeps the household awake howling or playing during the night!!
Any suggestions? :?

 

Get her spayed ASAP. This behavior will probably continue, and could become obnoxious, until she's either spayed or bred.

 

and next you'll have toms (as in cat :roll: ) hanging around spraying everything in sight YUCK

Any Siamese in her?

 

Thanks for your replies though I feel as though I have been given a telling off!! I will put an appointement on with the vet today. There have been a few gentleman callers at the door recently, but no spraying - yet.
No Siamese in her just part Burmilla + Ragdoll
Is this the reason she is not eating?
