Hello
I’m sorry to hear about your cat.
I think that you need to find a veterinarian or a veterinary technician who can show you how to do this. I would also recommend you start gentle physical therapy and feed canned food to keep the feces soft and able to pass more easily.
Puppies get hiccups OFTEN. I would investigate how you feed her, whether you allow her to run around right after food, whether you allow her to drink a lot of water after running around. Ideally, she should be calm at least a half hour before and after eating, and I wouldn’t allow her to guzzle water. I would also ask your vet for suggestions!
