When im holding Lily  aside from her huge tumors when you feel around her stomach area and her spine she feels like skin and bones. I dont know whats wrong wit her but maybe she is losing weight from carrying around the huge tumors. I dont know if this is a problem, because she seems to be eating just as she used to be, and she used to be very very fat. Is this a problem?

Ok well thanks alot, i will feed her alot and supplement her, but how exactly will i know if she has had enough, becuase so far she has not been acting any different or acting like she is fed up with life, she always gets excited to see me and almost falls out of the cage door. she gets cheese and zooms down the stairs to the bottom to eat it. well thanks for your help. ill keep sum updates posted if anything happens.

&& well i hate to talk about it but if it was time to put her to sleep then where do you take her and wat do you do.?

Oh and be very careful with the sugar and fat intake as both of these will feed and make the tumours grow even faster

I agree with all that's been said above.  As far as the hows and wheres, if you do a search (the button is at the top of the forum) for euthansia or PTS, you'll find many discussions on the things to ask your vet (if you don't have one prior to making the decision), and the most humane methods.  It's a hard thing to deal with, but, as long as she's bright and happy, it's a decision you can put off for a while.

All of her nutrients are feeding the tumor and not her.    What about Nutri Cal or Nutri Stat?  It's a high calorie supplement, like a gel type stuff they lick.  Most pet stores will have it somewhere in the dog or cat health section.

I looked at the case study posted above...it made me cry.  Those poor ratties are bred for qualtity not quality and that's what causes most of the girls to be so sick.   

No, you have to go a regular rat vet.  Those Store Vets are only associated with the animals in the store.

Now that I really KNOW from experience the best way to put the beloved ratties to sleep when the time comes, I made sure with each vet establishment (and any emergency places we had) near me first.  Now I know them.  I asked if the rat could first be given just oxygen then have isoflurine (sp) gas GRADUALLY added in the oxygen so the little one relaxes and goes to sleep as it increases.  When they are certain she/he is totally asleep (test the eye to see if it blinks when they barely touch it for no reaction), they continue the gas while they give the shot in the heart that stops the heart.  Also, I ask if I am going to be allowed to be with my rat (I don't want them dying alone or with strangers).  I have an emergency place for after hours at one vet office (the actual ER in our area says "no"--so I say "no" to them) and two vet offices that let me be with them and do it this way for me.  It is a personal choice to be with them--and, of course, depends on if you can do it--I cry the entire time, but reassure the staff that I won't go over the edge --only cry and tell my rattie good bye and "go to the  light" and that I love them.  We have found (the vets and I) that rather that the small mask made for their size or small animals, the large dog mask is much better--they don't feel like we are trying to push something onto their face--the large mask is more like a container they can sort of halfway crawl into or crawl all the way into if they choose.  Two I have held in their soft pouches on the table with them climing halfway or sometimes then all of the way into the mask on their own.  Another we put the pouch in a small aquarium-type container and they had the air go into the container.  In this way (the oxygen and just gradual increase in isofluorine) they don't feel choked or gasp to breathe--they breathe and relax and fall asleep.  Even the shot doesn't initiate any reaction because they are like us when asleep for surgery.  I even held Lily while she got the shot--and trust me, I WATCHED in every case to make sure there was no reaction of pain.  I am only explaining this in detail because I didn't know when I held poor Sophie and cried and told her I loved her for three hours while she gasped for air and finally died--because I had no idea it could be so much easier and peaceful or I would have RUSHED her to one of my "approved" vets that day.  Good luck to you--we love them so much!   Sherry

i did a search for exotic vets. 
good luck with your girl. 

I heard back from one of the vets that i emailed and they said that the cost would be about $52.00 and cremation is about anbother $50. [[I dont want to sound cheap or anything]] but our family doesnt have alot of money right now and i dont know if we are gonna be able to afford that, but i really really dont want her to have to go through such pain.. do other places vary in prices or is that wat its usually gonna cost?

That's a pretty common price. One of my vets charges $60, the other charges $80. It's just that iso gas isn't cheap and as far as euthanasia agent it depends on the quality of that as well and it is highly regulated. Some places are nice and do it cheaper for regular clients or clients in need but anymore vets are trying to steer away from euthanasia with treatment as much as possible. But if you truly think it's time I would find the means. Sometimes you can sell a couple of things (old video games, books, designer clothing, electronics etc.) or get a short term loan if you need to. There is also carecredit but I don't think Banfield takes that although other vets might.

You can keep her for a while and put her into the freezer until you can afford cremation as well. Some people cremate all of their rats together. That cremation price is very cheap and reasonable. I had a ferret cremated at cost and it was $150 (R.I.P. sweet Gidgy)

52.00 is kind of reasonable.  you can a. elect to bring her body home or b. elect for the mass cremation to save money.  you might want to call the other vet as some clinics don't like emailing on such a sensitive issue.   

I believe you will know.  Trust your instincts about your own pet. Hugs to you and the little one.
