Why is the kitten doing that?
My 3-month-old kitten has these spasms (especially after eating). Since we took it it has never been particularly good with the intestines, but since we changed the diet (on the advice of the vet), and we started giving it royal canin gastrointestinal kitten, it has worsened further with frequent attacks of diarrhoea and this spasms so much that we decided to return to the previous food. We took him to the vet several times and no one was able to help us. More common parasites and viruses have been excluded. Thanks to those who will help me
