Okay sounding poo???

[RaptorTrainer]

I totally flunked and disposed of the poop before creating this post. But Furiosa's poop has been diarrhea-ish as of late. He has not been loosing weight and has a good appetite. Half of his poop is a soft, firm brown while the other part is an orange color diarrhea. It has a smell, and I can see bits of undigested kale in it.
I'm thinking it's because he's eating a lot of carrots. I'm also thinking it's because I've been having difficulty keeping his basking spot warm ( the outside coldness always seeps into my room, so I've been putting a heater next to his tank too).
He has a reptisun 10.0, a 100 watt heat bulb with temp at about 80 degrees. I'm replacing both of them once I get the money, and taking him to the vet for a check up.
Should I take him to the vet now for a fecal, or should I try a alternate diet??

Here is his recent one. It is not runny and has a shape to it now, I'm gonna take that as a kinda good sign since I managed to rise the cage temp to 94 degrees F.

Might just be an upset stomach. That doesn't look too bad but I'd cut down on the carrots. I like to reference this chart for ideas on what to put into salads http://www.beautifuldragons.com/Nutrition.html

If you find the basking light temp too low perhaps buy a higher watt bulb. They are so much cheaper than the uvb to replace.

How old is your USB. If older than 6 months replace as soon as you are able to do so.
