Hitting "submit", the app was showing sentence "A catlike woman lazing on her sofa.". It seemed that the change of the sentence had been entered correctly.
But, nothing happened. You thought it's natural that nothing happened and said "This must be a kind of joke." However actual sound you made was a "meow".
You said "Mia----ow!" you tried to speak "What?! Why I'm making a cat sound?" in surprise. It made you say "catlike". Not only about saying, but also you can only behave in "catlike" way.
First you tried to find out how you changed. So you go to in front of the mirror in the bathroom to see if there is any change to your face or other body parts. Seemingly, you arw perfectly normal, however, you found some changes about your behaviors. Going to the bathroom, you found that your walking was "catlike", means you are using both your hands and feet to walk. Since you could only stand on all fours, you even had to lean against the sink to look in the mirror.
Also, it was including the change of your mental. The bathtub in the bathroom was full of water, and thinking about getting into it pretty frightened you.
Anyway, you know how the app works, and how you had been changed. You came back to sofa to see your phone on there.
Now the sentence on your phone was
"A catlike woman is watching a phone."
