I definitely recommend getting a second opinion. I've had several experiences where one vet wasn't quite sure of a situation but the second vet nailed it.

You mentioned she pants... Is she panting like she's having a hard time breathing or panting because it hurts her to poo?

Also I've had an experience where a vet told me to put my cat to sleep (CRF) when she was clearly still exhibiting a zest for life. I got a second opinion and that vet said he would not advise putting her down (which I had already decided but wanted reassurance). Well, long story short, she lived for more than a year after that initial diagnosis!
