Id be cynical enough to make sure she really has a cat and isnt selling the food on .......
It happend to be when I fostered .... Someone I vaguely knew, knew I had foster cats and expected me to bail her out when she ran out of cat food (allegedly) . She was supposed to be getting her benefit money the next day (havent we all hard that one) I didnt like the thought of a hungry cat so ....
I found she was catless but was selling the food (at a highly inflated price) to another neighbour who was housebound with illness and couldnt get out to buy cat food, or anything else for that matter. The "scrounger" claimed the food she had from me, free, was all our local supermarket had on offer. People can be
scumbags!!!
