I am leaving to go home for Christmas and I will be gone for about 3 weeks. One of my neighbors in my apartments is going to keep an eye on my cat for me while I'm gone. I also am going to ask her to water my plants. Kitty has an autofeeder and autowaterer but scooping out the box will be necessary. What is a good way to pay someone for doing this for me? Gift cards or cash? How much should I give her? Just not sure what is reasonable and customary in this situation, thanks in advance for advice.
