aww wbless him!
i have never had a noisy bun but Charlie did used to gurgle after meals. Bri's only noise is a sort of grunt before he thumps. Jack occasionallys grunts if she wants letting down, just before she rearranges your clothing :lol:
bless your bunster, he may well be chatting to you, and, well, it would eb rude not to reply!
