When I run out of cat food (which I have been trained to do infrequently) they get Emergency Tuna.
The know the words. I just have to walk into the sitting room and announce Emergency Tuna! and into the kitchen we go. They like Emergency Tuna I think almost more than normal cat food and I am comforting myself that they hear the phrase Emergency Tuna and translate it as "mmm yum treat". The alternative is that they are being gracious about my lax attitude because it is convenient, but in the Cat book of Chatelaine Crimes and Punishment it is being listed and the total is increasing. I hope their lack of opposable thumb means they haven't yet flicked to the latter half...
One of them has been very poorly this week and her appetite has been a bit off. This calls for Desperate Measures Sardines (in tomato sauce), the strong smell and taste encourages her to eat. This doesn't have the ring of Emergency Tuna but something about the rhythm means that when I do say it, the ill one (which ever one that might be at the time) knows it is for them, and the well one doesn't demand their share.
Emergency Tuna is for all Ocelots.
