This morning I noticed Peanut making a sort of 'chuffa' noise when I was holding him. It sounds like he may be sniffing around but I don't want to rule out the possibility of illness and then have worse problems. If he's still doing it later today then I will get him to the vets, I just wanted opinions on what the noise is, especially as Crumpet isn't doing it and I haven't heard it before.
