The other eye should also be coated with a little ointment (but a cotton swab should be changed), which is not a big problem. This is how my mouse was cured by me. It is recommended to cage separately; Change sawdust frequently, clean the cage frequently, keep the environment dry and the bottom of the cage clean, including any accessories inside, don't even let the molar stone go, and carefully clean the wire of the cage. Change into dry sawdust, be sure to clean it up, and remove the sawdust from the mouse toilet every day.
Do not use cat litter. Cat litter is a good place for bacteria culture, and mice may be allergic for a long time. My hamster used to be a little like this. Give it some little Leton eye drops or small animal eye drops. I gently wiped it around the eyes with a cotton swab dipped in eye drops, and the movement was gentle and the cotton swab was soft.
Eye inflammation may be caused by fire or infection. Next, we should pay attention to its hygiene, change the padding frequently and drink water frequently. Put less sawdust and order napkins with less sawdust.
If you give more fruits and vegetables, you should give it less angry food, such as pockmarked seeds, breadworms and peanut seeds.
I hope your eyes will recover soon. My hamster used to be like this, and it is still fine now.
I suggest you feed some cucumber or apple puree and dilute the glucose water. Or go straight to the vet.
Get hamsters for help! People there are very experienced, that's all. Don't throw it away. What a pity. All right, that's it.
I wish your rat a recovery. If you have any questions, leave me a message online. I am very enthusiastic. Ok, hehe.
