## Questions & Answers

**Q: sizing**
A: The size recommended by the manufacturers was incorrect.  I bought a medium size shirt for a cat who is roughly 11-12 lbs and it was too small.

**Q: What size to buy?**
A: SIZE	 WEIGHTS	          < 9 LBSM	          9 - 13 LBSL	          > 13 LBSThis is how I found out what size to buys. The thoundershirt does work good. Hope this help you

**Q: Can you attach a leash to it?**
A: You won't be able to walk your cat on a leash because the shirt is too relaxing. You'll have to carry your cat.

**Q: My cat screams and cries all the way to the vet and undergoes terrible stress.  He's fine when we get there.  Will the Thundershirt help?**
A: Probably. My cat has the cat version of Alzheimer's. When he starts howling at the top of his lungs, I put him in the shirt he stops howling and flops over. He seems OK for a while after that and I take the shirt off after about 15 minutes. This cat becomes Catzilla when taken to the vet and the shirt reduces the screaming and conniption fits by about 50%. It was worth the money.
