Strange / funny sound ?

[Dejan Pavlovic]

Hi everyone ! A few days ago we noticed that our Maggie sometimes produces a very strange (rhythmic) sound while sleeping , but not always - every other day . It sounds like when you clean the glass with the towel , it is rhythmic - every second one "toot" (it is not squeeking or sneezing) . And if we wake her up it stops. For instance this night it vas very loud , we woke her up, she stopped , got back to "bed" and it was all right . They were out later , and now they are sleeping a few hours and there is nothing to be heard , and the same thing happened two days ago , and before . Anyone knows what could it be ? She eats and drinks regulary , behaves normally , sleeps and plays with Bart (her mate) Bedding : Clean white paper on the bottom , hayand toilet paper (they dragged into their nest) , on the other part is wood shavings , but they don't sleep there...   Should we ignore it ?
