We have to get Frost fixed

We just got a call back and frost (our cat) can finally get into the vet to get fixed. It only costs $50.00 and we have it scheduled for next Saturday. I'm so nervous about it and I don't wanna take her in. She trusts me and now I am just taking her to get fixed and she doesn't even know! The place was like "oh you don't have to have a cage you can just put her in a duffle bag or a zipper pillow case." I'm sorry WHAT?! Are you freaking crazy lady? Do you want me to kill my cat to? I don't even want to put her in a kennel none the less a fricken pillow case! She's insane and I am taking my cat there to have SURGERY. I don't want to. Why can't frost just not get pregnant and be responsible. 

 

This picture is from today, frost is in the chair being all cute.

I know I am probably overreacting about this, but I have to drop her off at noon and then can't pick her up until 7 pm :( She was like well she can just stay the night and I went back to the "ARE YOU CRAZY LADY. you want me to give you my cat in a pillow case for the WHOLE NIGHT" Okay I didn't really say that, but I thought it. Like this woman thinks that I hate my cat or something. But at the end of the day it has to be done, and my other 4 cats all got fixed there like 2 years ago so I know the place is safe. I just am nervous. This is the first time we have taken her anywhere. She is very skiddish when it comes to meeting new people. We think this is because she was a rescue. We found her on our back porch and she was probably under a year old. It was over the winter two years ago and it was supposed to be -40 degrees that night and for about the next week. So we brought her in and she was supposed to be found a new home or her old home that week, but we fell in love with her. When no one claimed to have owned her from before we couldn't get rid of her. She was so sweet and it took her so long to warm up to us we just couldn't imagine how she would act in a new home. 

Dakota and I love her to death and she favors just us over everyone too. It's funny to watch her play with blitzen because when she first came here blitz HATED cats. Like he couldn't be left in the room with one alone. But he eventually warmed up to her and look at them now (See above picture). I am just worried that something might happen to her when she goes, but I am sure everything will be fine.
