This test is a bit late but at least I got it done and out of the way.
I apologize for any confusion. As cats have fur already, they don't typically need a sweater to keep warm and in fact most of them may not tolerate to have one. A sweater also can be a discomfort to them, as they don't have the ability to take it off if they get too warm.
Crochet projects for cats can include toys, blankets, or beds that they can enjoy and feel comfortable with.
If you are still interested in making a sweater for your cat, I recommend consulting with a veterinarian for guidance.
