mouse has swelling which began beneath left eye and that eye

Customer Question

mouse has swelling which began beneath left eye and that eye seems to be bulging - the eye is clear and black, no redness around - just puffy - may tear but is not crusty or yellow and isn't tearing enough to be noticible - he moves around a lot so it is hard to get a good look. he is otherwise fat soft and healthy - has all his hair and ears

Thank you

My name is Joan and I am a Vet Tech with special interest in small exotic mammals. What you are describing with the swelling under the eye is common when there is a dental problem. If this is let go over time it can cause more serious issues. You can read about Dental problems here and if you scroll down, you will see a swollen cheek as one of the problems: Since the tooth root goes up into the scull it can also affect the eye. Most likely there is an infection in the tooth root. I hate to tell you this, but it will need to be addressed by a Vet familiar with mice and rats. You can find Rat Vets here: You will need to type the word member in each blank and it will bring up a list. The Vet will most likely start Brownie on an antibiotic to help clear the infection. I would make sure Brownie has plenty of chew toys and see the Vet tomorrow. You can put a Drop of Sterile Saline(the type contact lens wearers use) in the eye to soothe it if it seems to bother him. Please let me know if I can assist you further. My goal is to give you 100% Excellent Service. Joan

Hi Lisa,

I'm just following up on our conversation about Brownie. How is everything going?
