:thumbsup: great info keep us up to date.
i thought i did a test on the cats, but i did not. the das has no test. besides a rattle or the rotten smell, how do you test to see if a cat is bad and identify right from left problem. i hope its not the cats! i see another member had to replace one due to similar symptoms. my symptoms start once normal temp is reached.
