Steps
1. Shift them somewhere where the barf is simpler to fresh, just in situation.
2. Pat them carefully but strongly on the center of the returning. Different this with smoother swings to ease the cat, and say something in a relaxing overall tone while you do this.
3. If it's not operating, use your other side to raise their front side end so they're in a semi-standing place. Keep drawing them as in #2.
4. Pay interest to the audio of the retching. If it is getting more and more extreme, they're probably about to barf. Set them down and pat them reassuringly.
5. If they do barf, don't get mad at them. They have no more management over nausea than a individual does. They're nausea, so be supportive.
6. If the retching forms down and prevents, hug them a bit and keep drawing as in #2. You will probably listen to some smooth burbling appears to be in their neck or abdomen. Keep drawing them until this forms down.
Tips
Cat barf is simpler to fresh off of real wood ground than rug or furnishings.
Warnings
If your cat usually delivers up slimy paintballs of fur, it's just hairballs. If they're mentioning more large gooey things, that's real meals. Hairballs are regular, especially in a long-haired cat. Barfing up meals is regular sometimes, particularly when they've just consumed something new, but if it's regular you should consider a journey to the vet.
If they carry up a milky white-colored material, take them to the vet IMMEDIATELY. This is a indication of renal failing.
