I took my veiled chameleon to the vet about a month ago in response to some swelling in his neck area. Blood tests came back okay except for a raised white count that indicated infection. Still waiting on x-ray results. I started him on injections of ceftazidime every three days and am nearing the end of the prescribed amount and I noticed he has barely defecated at all in the past two weeks. There are a few droppings but they are very small. He also isn't drinking as much as he usually does. I gave him a shower yesterday to try to encourage him to defecate but it didn't help and he didn't even drink while in the shower. Interestingly enough, I filled his dripper with water after I put him back in his cage and he went and sat under it without drinking as if he wasn't ready for his shower to end. I was wondering if anyone has had any experience with this drug and if it would cause this sort of problem. He seems to be okay otherwise, if slightly less active than normal. He is usually most active in the morning when I am away so it's hard to be sure. Any suggestions?
