Hey everyone

Sorry for posting another new thread within like a week but I have a serious question. Its about my mouse Pretzel. I have had him for about 2 months and everything is going really well he loves to run around on my shoulders and snuggle in my hoodie but today when I took him out he started sneezing. He always sneezed a little when walking around but i figured that it was the same as with rats that when they explore they sneeze sometimes. So i wasnt worried until his sneezes were followed with raspy breathing and the sneezes started to sound deeper and raspy as well. I held him against my ear (where he continued to sneeze) and heard the sort of rattling there. I immediately thought of taking him to the vet of course but after he stopped sneezing he sounded perfectly fine and even his lungs (from what i could hear) sounded fine.
Any advice on what I can do about this? Should I go to the vet? Or should I just wait a little since he seems to be fine now?

Thanks in advance for any tips!
