I have a 4year old french lop that has always been fit and healthy. I got her at a year so never knew if she had been speyed. Yesterday afternoon Daisy and her conti partner were in the garden as usual and all seemed well. When I went to put them back in their shed I felt she did not seem quite right. So I fed them some greens as usual and she refused them. i left it half an hour and then took her indoors to watch her closer. Still no interest in food so trip to tesco to get some herbs etc. No interest, which is unusual. She had shaken her head a few times recently but when I checked her ears all looked good. So I thought I would give her a dose of metacam in case she was in pain. After a while I managed to get her to eat quite a lot. So decided to put heater on and put her back with her conti partner rather than keeping her in the house overnight.This morning not her self and not eating. So I rushed her to the vets at 9am. Her ears were fine, her teeth looked fine but when he felt her abdomen and he felt a hard lump, which could possibly be in the uterine area.So he took her in to X-ray her. Phone call this afternoon said it wasn't a bladder stone which I didn't think it was cos there had been no straining. But the mass did not show on X-ray but he can feel it.So he has decided to keep her in and has put her on a drip and is stabilising her with the thought of operating on her tomorrow to see what the mass is. Naturally I am really concerned that she will pull through all this. Any thoughts or ideas on whether you think a small mass would be enough to stop her eating and what is the head shaking about? I wondered if something else could be going on to put her off her food and the lump was a secondary issue. I asked him if her spine was ok as was wondering if it was arthritis and the pain could be making her shake her head and go off food, But he said it looked ok. Just wanted your ideas as have to make decision in the morning about op. X
