A while back I made a post about my male neutered rabbit's really stinky (non cecal) poos. I took him to the vet and the vet wasn't concerned about it and everything else checked out fine (I also had him tested for a uti). It's getting worse and so are is litter box habits. I recently bonded him with Wilbur, however the increase in odor and decrease in litter box habits started a couple weeks before I started bonding them. He also pees outside the litter box about once a day. The litter box habits I'm working on, I know it can take some time, especially with the recent bond. The smell though is getting near unbearable. I have confined him and Wilbur to my room for now. It's not his glands, they are clean. Does any have any idea what this could be? Is it just territorial? Is there anything I can do?

At first they were dry, but now they are more sticky, shiny, and darker colored.
