If I were you, allergies or none, I'd adopt her and take her with you for this trip.

Failing that, I'd get someone in your local circle of friends to take her in your absence and feed her.

As a LAST resort, I'd take her to the pound and tell them I was a potential adopter on my return --- so she isn't exterminated.

And just to be on the safe side, I'd check the lost cat notices on your return. If none describe her, I'd adopt her.

Do you have a friend or neighbour who would be willing to put food/water out for Tiny? I think that's the best scenario.

Ok. I have no cat advice, except maybe pick up one of those bin feeder things that drops out food as the cat eats it (and maybe a water thing too).

But it's hilarious to me that schroedinger is suggesting to make the cat a box. Anyone else?
