Manx cat - uncontrollable shaking

Question
The shaking is more like shivering, but it seems to be mostly her head that shivers.  Most of the time she can run & she plays, eats & drinks well. If it is pain, can I give her a little aspirin?

I have a 12 year old manx kitty.  She has had problems with her hind legs in that she is very splay-footed and sometimes it hurts to walk.  I've found that massaging her hind area, the hip, and leg help.  She stops hurting & walks better.  In the last week, I've noticed that when her walking gets bad, she starts shaking - like shivering - her head.  She acts a little like she wants to scratch her head & she shrinks a little.  It's very scary.  Any ideas?

I can't quite picture what you mean by shaking her head, but it could simply be from pain if her hips are that bad.  I definitely think you need to take her in and have her examined by a vet. It's also possible she could have some sort of issue with her ears if she is shaking her head.

Answer
Never give your cat aspirin unless a veterinarian has instructed you do to so.  Cats are very sensitive to NSAIDs (Non steroidal anti-inflammatory drugs).  The only other thing that I can think of that could be causing her shivering is something neurological.  I'm sorry I wish I could be more helpful.  If she is running and playing, and eating well then that is a very good sign.  If her symptoms get worse, definitely take her to the vet.
