Pet rats

1 of my rats are really ill but I dont have money to take het to the vets what is the best thing to do I have thort into putting her down my self but how do I do it so she dont die in pain

there is no way for you to put down the rat yoursefl. just make sure you put the rat in it's own seprate cage, making sure it is comfortable and not harassed by other rats. When the time comes, the rat will die, and you will remove the body and do with it what you like (AKA buringing it, ETC)
BUT: If you do get the money, take the rat to the vet! you will need to save up lots of money, and ask for donations. although, I wouldn't recommnd this, the rat may die anyway.

hey guys no worries about her she absolutly fine she pregnant but I just need to fatten her up a bit
