Hi there. Just a little concerned about my foster kitten. I gave her some canned tuna as a treat last night and this evening she had vomited and had diarrhoea. Is my idiotic thinking to blame for this? . She is also sleeping atm and normally at this time she Is playing, and she also seems not herself. Should I be concerned or will she be ok?

The tuna could have caused an upset stomach. If this is the case, it shouldn’t last longer than 24 hours. If she isn’t back to normal tomorrow morning, it is a good idea to have Honey checked out by the vet for other causes of illness.
