It looks like if we have found the reason for the vomiting of the cat Linos. I found that one of the food source I recently use is not grain free. There was always the assumption that he had a grain allergy. So it was slightly my fault. So keep fingers crossed that this was the reason.

The formidable Italian player made it to Wimbledon three times, turning heads with every outfit.
The sick cat becomes better from day to day but he still has to be fed in small portions. Nevertheless he shows interest in his surroundings again and visited the balcony. #catsofbluesky#cats
This morning I decided to go to the emergency vet with the cat. They didn’t do much but confirm that the belly is still soft and nothing obviously wrong. He got some Cortizone and painkiller injection. I’ve got some special high energy food in a tin and liquid food in a bottle.
The cat is still not eating properly. The first thoughts about not going on holiday on Monday came in my mind. Still two days for improvement. On Saturday I planned to go to my parents and from there on Monday to the Netherlands. #cats#catsofbluesky 
The cat is sick. In the night from Sunday to Monday he vomit. Around 3 AM. The next morning he wasn’t really keen on food. But later he ate some, especially some pieces of dry food. I hoped the episode was over. This morning he spit a bit, not much but he hadn’t eaten anyway.
