If I had my friend/neighbor feed my pets when I was away on a long weekend, and I gave her some money and additional thank you gift which she didn't acknowledge, should I ask if it was acceptable?

I was recently away on a long weekend. I asked my neighbor, who is also someone I am friendly with, if she would feed my pets once. She did it twice, which was very nice. I told her just to feed them, and not to bother with the litter, so she didn’t. We didn’t discuss payment, or if she would even want payment. She did it once before for me, and she asked for souvenirs, which I had brought her back (about $50 worth). This time, as Easter was coming (and yes, she does celebrate Easter) I thought I would give her a monetary gift and some Easter stuff, which I thought would add to the fun. So I put $20 in a card, and put the card in an Easter basket with some Easter stuff and personal stuff (like bath stuff). Doing errands that day, I saw hot cross buns at the store so I bought her a pack of them, also.

I left it all with her hubby, because she was not home when I dropped it off. I know their dog was very sick and put to sleep within a few days of this, so I’m not sure if she was caught up with the sick dog issue, or if the payment wasn’t sufficient, or if she just forgot, or if a thank you gift doesn’t have to be acknowledged. However, I don’t want to ask if it’s unnecessary to ask and appear to be fishing for compliments.

What do you think?
