My cat is 9 years old and has been to 5 homes. He pees but will not poop in the litter box. He had constipation when he first came here and I have 3 litter boxes and have tried all kinds of litter. He will sit right in front of me and poop. I have not yelled at him while he is doing this as to not exacerbate the problem. I had him going in the litter box consistently over the winter but now that summer has come and the windows are open he will not poop in the litter box, I am at my wits end. He is happy and healthy otherwise. I have used the enzyme cleaners, calming spray, and composure to no avail. I am out of suggestions and he is not afraid of me at all and it is just me in the home. I have even contacted Jackson Galaxy with no response. I can't continue to have him do this.
