Have you ever had a cat who got steroid shots?

Yes, I've had two cats that have had to get steroid shots. One has to get them twice a year for an idiopathic sinus condition, and another one was so allergic to flea bites he would have to get steroid shots. Hasn't hurt them, certainly helped them, and hasn't shortened their lives. However, they do compete in a lot of Body Builder competitions....

i once gave my cat a puff of weed later he developed a heroin addiction and is now selling his body on the street

Yes, and she acted funny for a week... try not to let your cat outside..  Chae-won??  I had a Chae won in a class...

at least they worked, ive never had a cat
