Thanks once again everyone.
Tonight's IV did not go so well. I was trying to keep it from falling out like it kept doing last time, so I went a little deeper. My poor kitty was bleeding when I got done I just felt awful!
I'm going to keep trying to get it right. I hope it's one of those things that gets easier as you do it and get a feel for it................

KAK, I know what you mean about trying to do it alone- it's tough.

Koxka- I should ask the vet about the catheter like you mentioned.
