Yeah, I can. Loki complains and whines a lot! It's this "MUROW" or just "RROW". Possum has this little sweet "mew" and sometimes does this little chirp sound. His voice is real high and it sounds feminine to me. He was neutered way before he matured. However I had to take him to the vet once, and his meows got significantly deeper to voice his displeasure of being in the cat carrier. It was quite shocking at the time, but it's funny now.
