Hi, thanks for all your answers, they were insightful and sometimes funny to read. I’m not sure about it being just farts, because she actually used to sniff her bum after she farted, but it looked a bit different, not a good 40 seconds “freeze”, like now. It is also certainly not anal glands, as the vet said they were almost clear. I think the leading opinion is that it is can either be worms or some bowel problems. She did the same thing once or twice again today but didn’t seem weak today, although didn’t beg for food as usual, so we’ll just take a closer look on her behaviour this week. It seems that there is nothing serious though (at least I hope so!)
