Bramble was sick overnight... dark brown , food coloured and bright orange bile... no food in it. She seemed ok otherwise, has done her usual 2 poos this morning so gave her her morning kibble and then 6 hours later she has been sick again... yellow frothy bile..quite a lot of it. She doesn;t seem too bad otherwise. Think I had better starve her tonight .. can't imagine whats done it...Ideas anyone? why does it happen at weekends too!
