A couple weeks ago I took my 2 year old rat to the vets just to check on her breathing. The vet said she was perfectly find nothing to worry. So I went home and just went day by day. I noticed she wasn't really eating and drinking little and acting a little weird. I decided to weigh her and she was 412g and before on the week prior when she was at the vets she was about 522g so she lost about 100 grams. A couple days before taking her I noticed she was loosing her balance. I took her to the vets and he confirmed my suspicion of her having an ear infection. He prescribed her an a Steroid, Antibiotic and some Nausea medication so shell be able to eat. He suggested some baby food and Ensure Nutrition Shake and some cantaloupe because she loves that. She slowly began to eat but at 4 days later she's loosing more weight and I don't know what to do. Please give any information that could help
