Why does my cat have muscle tremors when sitting or lying down?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 3 lbs

My cat is exhibiting sharp tremors, a quick muscle contraction, near the front torso. Seems to happen in clusters.Have been giving Temptations food, will cut that out. We share some salmon at times, high in fat oil. Cat is still active, jumps and runs, only see tremors when sitting or lying.

Hi there, thanks for using Petco Pet Education Center, formerly Petcoach. These tremors could be a simple thing such as mild irritation to the skin in that area, or something much more concerning such as petit seizures or a symptom of a toxicity. An exam with a vet would really be necessary to determine what's causing Udel's tremors. It's definitely a good sign that she's still active, and if she's acting pretty normal and eating well then you can likely monitor her for a day or two - but if this continues then I recommend scheduling an exam with your vet. If you can, I recommend trying to capture a little video of the tremors, just in case she doesn't do them at the vet's office, so they can see what you're noticing at home. If your vet is providing curbside care, you could e-mail the video for them to see. In the meantime, if Udel starts acting sick, lethargic, unsteady on her feet, or shows any other concerning signs of progressing symptoms, then an ER visit may be necessary today as I'd be worried about a possible toxicity. Hope that helps!
