Cats/Muscle Cramps?

Hi Paul and Norm

My 20 yr old cat has been having the same type of muscle cramps that you describe.  Its been happening for the last couple of months or so. It really scared me the first time I saw her. Just after eating, she lifter her front right paw high up in the air, and then lifted on her hind legs, overbalanced and tipped over.  I originally thought that it might be a stroke or seizure, however there has been no paralysis nor was she frothing.  After the cramp passes (a minute or so), she is back to her calm relaxed self.  I can only describe it as a cramp, as sometimes if she is eating, or cleaning, or has been asleep for a long time (which she does!) and will suddenly move, she will suffer the cramp.  Hope your 17 yr old is well and fuzzy.  leanne

My cat started experiencing the exact same symptoms about 18 months ago and is still having them.  He is only twelve years old but has since then been diagnosed with a hyperactive thyroid.  He is on tablets but very sadly is now suffering from heart failure which was only discovered 12 months after the thyroid problem even though he has three monthly checkups at the vet.  Anybody reading this who has a cat with a hyperactive thyroid please keep a check on your cats breathing rate (approx. 25 breaths per minute is good) and at the first sign of a cough go to see your vet straight away.  Heart failure is a terrible thing to see your cat suffer from with very little hope unless it is caught in the early stages, which is quite unusual as cats hide their symptoms very well.

Keep a look out and take your cat back to the vets if you do not get an answer first time.

my 12 year old cat has exactly the same symptoms. She has just been diagnosed with Chronic Obstructive Pulmonary Disease and is being treated with a dilator (pill) plus antibiotic (a week on that, so far).  I read that this could happen if there is inflammation.  I do not know if it will go away after....

Our cat too has had this issue. It's been ongoing for several years. We've heard it categorized as a syncopal episode, but from what we've read it doesn't seem to fit.

In our cat's case, sometimes (as tonight) the "cramping" behavior starts in the forelimbs, but usually the onset is at her left rear limb, with both curling up into her belly. As with Norman's cat, she purrs, seems lucid and otherwise unperturbed, and after recovering apparently returns to normal. She's 17 now. We first saw her suffering this syndrome in 2005. It doesn't generally seemed to have gotten more frequent or intense, though the one tonight was the second in three days, which is unusual.

Your Cat strongly sounds like she has a heart condition, Hyperthyroidism often negatively affects the heart, my Cat also has Hyperthyroid and experienced the front leg cramp and later hind legs collapsed , she recovered from both.  But I've read on Internet where the heart can cause all of this via poor circulation and very possibly a blot clot which if not treated could eventually kill the Cat.  The heart condition is commonly called saddle thrombus.  Google the name and get all the information.

Your Cat needs to receive a heart Ultra Sound, as mine did that disclosed her heart muscle has thickened.  

Now I'm gonna go to a Vet who specializes in Internal Medicine to search to see if she has a blood clot and to get medicine to break it up, hopefully.  Because, lately her hind legs again are weakening and I fear the collapse is returning, also she is ver tired.
