Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Fiorre Flamma!
I recommend that she be seen by a Vet as soon as possible due to the heavy breathing. She looks pretty sick in your pictures.
Possible causes of a bloated stomach in a kitten are: intestinal parasites, constipation, and feline infectious peritonitis. All of these things are treated differently and have different outcomes.
The best thing for Fiorre is to see a Vet for an exam and testing.
I hope this helps and I wish Fiorre a speedy recovery!
