something is wrong with sparkle

I have a kitten that was running through the house climbing everything and just having a good time nothing unusual. Now she isn't moving I don't understand how she went from playful and happy to crying and immobile in less than an hour. She is only a little less than 3 months old. I've had cats majority of my life and I've never seen anything like this. Has anyone ever had something like this happen and if so any idea what caused this drastic change in sparkle.

If the change is that drastic, it sounds like you really need to get her into the right right away.

Good luck!

Thanks I'm waiting for my husband to get here. Its just that sparkle is my 5 yr old sons kitten and if she's not OK when he gets home he's going to be heartbroken.

Have you already called the vet and advised them of the situation and that you'll be bringing her in?  They might have some advice over the phone.

I hope it's nothing serious.
