Hi everyone,

My pastel ball python is a year and a half weighing 682grams.

He had a bad shed and I bathed him and got it all off.

I changed his bedding and viv (from aspen to lignocel and from 2.5 ft to 4ft).

Since these changes I have noticed him whistling like a human would with a blocked nose.

I took him to the vet on Saturday and they said there are no signs of RI.

Any ideas what it could be as he is still doing it.

Thanks
