My kitten is having gooey poop and has a bloated belly after eating. Deworming did not herald results. She eats often but cries when in the tray.

Loose, runny poop and a bloated belly could be due to a few different things. In a kitten that age, intestinal parasites would be my first concern, so good for you for deworming her right off the bat. But, there are some other parasites besides just worms that kittens can get, such as a microscopic parasite called coccidia, and regular dewormer won't get rid of them. She could also have some other illness causing the diarrhea and bloating. Since deworming her hasn't solved the problem, I would recommend having her examined by a vet - he/she can do a simple fecal test to check for coccidia or other problems, and talk to you about other testing if needed.

Intestinal parasites are just one potential cause for her swollen belly. Ideally, she should be physically examined by your veterinarian to diagnose and treat the underlying cause.
Submit a stool sample to diagnose intestinal parasites. Your veterinarian will likely recommend or administer a broad spectrum dewormer anyway given Smoker's age.
Deworming should be repeated every two weeks for 3 or 4 treatments. Afterwards, she can be placed on a monthly preventive, especially if she will be an outdoor cat.

It could be due to the deworming treatment killing the worms in Simon's stomach. Intestinal worms are common in puppies. As long as he's otherwise acting normally, I'd keep an eye on him for now. If he has diarrhea, blood in his poop, vomits, is lethargic, or has a loss of appetite, have him seen by a vet. Best of luck.

Thank you for submitting your question regarding your kitten. I recommend that he has fecal testing as I suspect parasites are still the problem. It is not uncommon for a kitten to be infected with more than one type of parasite. The feces should be evaluated under a microscope if possible so any remaining parasites can be identified and properly treated. I hope this information helps!
