NO HEARTWORM! Woohoo!
They do have some intestinal worms (expected) and Mustard has what appears to be an abscessed bite wound.
But he got it drained and got some antibiotics for it. And I've got some Panacur for those gut worms. Other than that, the vet said they're well on they're way to recovery.
We also believe that Mustard is around 3 years or so, and Ketchup is around 7.
Project Rescue Chicago and The Trio Foundation took lots of pics are going to post them on their Facebook pages and try to get them cross-posted. I've been advertising them at work, so fingers crossed.
