Our cat has a mostly consistent dry food diet, but we very occasionally give her small amounts of wet food (gourmet gold pates). Until recently this has been fine but the last few times she has vomited afterwards.
At this point you'll be thinking 'just don't give her the wet food then?' 
The problem is our cat needs medication (in pill form) twice a day, every day. If we are ever away overnight we set a feeding timer including a teaspoon of wet food with the pill hidden inside. This has been working well for years, until now when the last few times we have gone away and come back to a house covered in vomit 
Anyone experienced similar? Could they have just changed the formulation of the food or something and it now doesn't agree with her? Does anyone know any other pate-type cat foods suitable for concealing pills?
