Tikva was fine yesterday, ate as usual, went to bed at around 11pm and slept until just before 8 this morning when I heard her retching, and when I put the light on she was throwing up a bit. Not just a bit of bile as it looked a bit darker and thicker. Came out of her crate, went out and had a normal pee and a normal poo, but then came in and just looked miserable. I offered her a plain biscuit which she took and jumped back on the couch but did not touch it, then threw up again - and would not let me near the couch to wipe/clean it - I think she was guarding the biscuit which she did not want but did not want me to take it from her. She has been out again for another pee, which gave me a chance to remove the biscuit from the couch and clean where she had thrown up on it - just a bit of clear liquid that time, came in and started searching for the biscuit. Tikki is definitely not herself and even refused the piece of banana I offered her - totally unlike her as she adores bananas. It is now well past her breakfast time but she is obviously not interested in food and I am not going to offer her anything as I think it is better to wait until she asks for something. I do not think there is anything else I can do at the moment, but of course I am a bit concerned as she definitely is not 100% well at the moment.
