I have to agree with alyssa rat on this one night yes you should always have backup money but sometimes things just happen i would put my kids before my rats ANY day a rat is prone to upper respitory problems but if you do everything properly then they are not as severe. If alyssa is still eating and drinking and active then there is nothing wrong with wiating things out a bit Alyssa i would at least call a vet and ask them what they thought about it even try and see if they will work something out with a payment plan (*rolls my eyes* vets around here are heartless) but if you don't have it don't feel guilty alyssa rat knows you are doing your best for her
