My cat has a bad pelvic fracture that I didn't know about until one day I took her in and out of surprise it was found, along with a bullet lodged a few inches from her spine. I had found her as a stray and took her in - She walked fine and acted fine. Her doctor informed me her injuries were done on purpose and we were all shocked that she recovered without any medical attention.
She has chronic constipation and the lactulose was not working, she's had several surgeries and it seemed to really effect her, she's an old lady and I seriously got tired of her going through this every month and having all these surgeries to remove it and started thinking it was finally time to let her go. Out of desperation I went to the store and tried one last thing before I took her in which, I was going to do the following day. I bought some Mineral Oil and gave her an enema - it was so huge, there was no way she'd pass it, and you could see it. I've tried to take it out myself, but it was too painful for her. It was horrible and she got to the point, where she would sleep with her rear in the air. I started the enema of mineral oil, the next day looked at her rear it it was gone. I looked in the litter box and there it was. She had passed it during the night. I was so exstatic I couldn't believe it and still to this day I still use the Mineral Oil and it does work. It lubricates them so they can go easily.
BUT, DON'T GIVE IT BY MOUTH, WHEN YOU SQUIRT IT INTO THE MOUTH, THE CAT CAN EASILY ASPIRATE IT AND IT COULD CAUSE LUNG PROBLEMS AND OTHER PROBLEMS. USING AS AN ENEMA DOES WORK.
