Hi, I’m taking care of a sweet kitty BW, whom just had a blocked urethra. He’s able to pee on his own yet I still need to syringe feed him & I have not seen him poop in a few days. In case he is constipated I need to know if slippery elm works for constipation also. I buy it from only natural pet so its alcohol free & in syrup form. I also give him proviable, D-mannose, fluids, & pinch of nutritional yeast. If anyone knows i would really appreciate your help. Thankyou.
