She's shaking or shivering

Hi everyone. Please help me before I spend another 100 dollars at the vet. My little kitten, 15 week old Lulu started shivering or shaking over the weekend. The only thing that has changed is I have boxes in the living room because we're moving and that might have stressed her out. She was just at the vet two weeks ago and was fine until like Saturday night. Now she slept the whole weekend-only played for about 5 minutes Friday, Saturday, and Sunday. Please shed some light?!

I cant say ... call the vet at least and discribe what is going on..

Could be low blood sugar, sometimes kittens have dips but she is a little older for it. You could try putting a little corn syrup on her gums to see if there is some improvement. Talking to the vet (not a tech) over the phone should let you know if its serious enough to take her in though.

Yes, please at ;east call the Vet and ask what you should do,,,
