Hi, I have been the proud mommy of many rats over the years. Normally when we come across an issue we can take care of it ourselves, but I decided to sign up and ask here. Right now we have two precious boys who are near 2 years old, but doing well. The one we'll be talking about today is Dumplin, the rat with the cutest markings I have ever seen in my life, and who (along with our other babies) I rescued from being food for birds of prey. These boys are all very special to us Dumplin sneezes a lot in the morning and makes squeaky noises when he does it (almost like he has mucous, but not enough to make his breathing sound weird). Every time I check his breathing and it sounds fine. He is eating and drinking well, not losing weight, and is very happy and alert. He isn't sick because we have two other rats who aren't affected. We think that he has allergies, and we have always done form the beginning things that will help with that (paper bedding changed every day, stuff like that). He might just be very sensitive. We're thinking that now he's gotten a bit older he's even more sensitive to things like the Tide we use for their towels and whatnot. We are planning to get some perfume-free detergent, clean the house, and give him a bath. I am wondering if there is anything else we can do to help my baby Doomp feel as good as he possibly can, and stay healthy enough to enjoy his second Christmas to the fullest Thanks!
