My dog while a sleep seems to twitch in his hind end

My cat is having small tremors My cat Shadow (13 yrs old) loves to jump up on top of my daughter or I when we're lying down. He'll sit down, do "piddy paws" (kneading), then eventually he'll lay down right there on top of us and go to sleep. Lately though when he does this, he seems to twitch in his hind end and won't sit completely on his hind end. He doesn't appear to twitch or not sit properly at any other time. He does not appear to be in pain.Thanks for your time, Michelle

    Some mild twitching while a pet is sleeping is considered normal, for cat sleep and dog sleep.  Excessive twitching or any lameness (limping) may be due to arthritis.  Trembling can be a sigh of pain.

    Arthritis is often missed during a physical exam or during a discussion with a geriatric cat owner.  Why?  Because cats with arthritis do not act like people or dogs.  Arthritic cats often do not limp like a dog.  Rather they just stop moving around as much as normal which is often just attributed to age.  The most common joint for arthritis in cats is the elbow joints,  Reluctance to jump up and down from furniture may be noted.  Opting to lay on the floor rather than the sofa may occur.  Sometimes cats will change sleeping locations rather than be bumped or rolled about as their owner sleeps.  Watch closely for any such signs. 

    Another thing to check for just in case would be fleas.  This has been a bad year for fleas and many people are battling them that normally do not have a problem.  Use a flea comb and comb the cat from head to toe.  Fleas often congregate on the back just in front of the tail.  Look through the hair closely for live fleas or flea droppings which look like coffee grounds.  If you find any treat with a high quality flea product from your veterinarian.

  • Why does my dog experience tremors & seizure like symptoms after taking Enalapril

    How often do you see that Enalapril 2.5mg BID (for a 20lb M dog) causes seizures? My little guy has had seizure activity—lasting hours each time—about an hour after each Enalapril dose. It took 3 doses before I put together the puzzle, as he has other health issues and I had to rule-out his other medications before I could get to the root of the problem. Thank You.

  • My 4 month old puppy has had about 4 episodes of front leg spasms

    What could these front leg spasms be? My 4 month old miniature schnauzer has had about 4 episodes of front leg spasms since i've had him. His front legs go rigid as if he's got cramp. I don't think it's epilepsy as he's lucid during these episodes and totally fine afterwards once his legs are ok again. I was just wondering if it's something simple. I was going to take him to the vet, but once it's finished he's fine again so they would not see anything wrong.

    We adopted a kitten at 5 weeks old who was found alone in the woods abandoned. He was pretty active for a kitten but did show some lack of coordination and had a bit of a bobblehead. During our vacation, he was being watched by my mom and when we returned he was not the same kitten. He was now very inactive and could not walk straight. It looked as though he could not keep his back legs up and he walked sideways falling down all the time. His purring also had diminished.My kitten is losing weight and it was previously thought he had cerebellar hypoplasia but now the vet is not so certain...
