Kitten dragging butt & stretching out back legs??

[waitingwithhope]

My 4 month old kitten, who has had all her first vaccinations & deworming is now doing something really odd- she is kind of dragging her butt and then extending her back legs in an odd manner, even when walking. She looks completely uncomfortable. About a month ago she did recover from the calicivirus (which did make her walk funny) but this looks different. I checked her littler box for worms, checked her for fleas and looked at her rectum but didn't see anything odd. I tried to gently place a warm cloth on her rectum area (there is not poop there or anything) and she seemed to understand I was trying to help. She is now following me around moaning and meowing. Other than that she is acting normal, chasing her toys and eating and drinking fine. Poop seems normal. Any ideas? I hate to rush her to to vet unless I have to...but should I be rushing her to the vet? Is this serious? Any ideas??

She may have impacted anal glands which can be very uncomfortable,  or even more likely,  she is going into her first "heat" or menstrual cycle.  If she is already spayed, than it would not be a heat cycle, of course.  Your vet will be able to establish the cause.

Thank you, I researched more online and I think you are correct- she is probably going into her first "heat". We were waiting to get her spayed until March (so she'd be 5-6 months old-the recommended age from our vet) but now I worry I'm too late!! Hopefully she can hold off until I can get her to the vet next week.
