Oh, it sucks she is a senior rattie. I wish they lived longer! since she is doing fine now maybe you can get that tumor stuff and try to slow it down a bit and see if that makes her life better when it gets to be closer to"that time". As long as she can get around, eat , drink and still loves her treats that's great! As long as you give her plenty of love and I am sure she knows this, all you can do is make the rest of her time here as pleasent as possible....and I can see you are doing just that! Keep up the good work! Ratties need more loving caring owners such as yourself!
