Hi. I’m hoping you guys can help me. I have a 3 yr old male that we found outside when he was only 4weeks old. He’s always had a small issue with anxiety, but now he’s suffering from constipation. This has been going on since October, and he won’t go in his litter box. I have to feed him mirilax to force him to poop. When he finally can’t hold it anymore and goes, he growls and then darts off. He also lets small nuggets out and runs from that, too. Now he is making a sore on his stomach to try to get to his intestines. Has anyone experienced this? And do you have any advice on how to help him? The vet is only concerned with whether he is going or not. I hate seeing him like this.
