About 3 days ago I ran out of cat food and obviously I couldn't just nip out with current circumstances so just for that evening I split a tin of tuna in water and a tiny bit of leftover salmon and sprinkled with their usual dry food. Now for the last 3 days neither want to eat their food! Both cry in the morning like they are hungry but soon as I put their food down they aren't interested, to the point where my boy is going out and eating what he can find and this morning has been sick! What can I do?! Their current wet food is whiskas in jelly 1+
