Well Popsie had to go into the vet for his monthy enema today.
I only say that because since September he's been getting constipated once a month. He got plugged up while trying to poo again. It's so weird. I give him his lactulose twice a day without fail and everything is fine. Then all of a sudden, BAM, he's constipated. He's ok now. I'll have to see how next month goes.
