More refunds in last week than the previous 6 months

I’ve only been selling on Amazon since May of 2024. I’ve had few refunds for my product and my product is one that Amazon doesn’t require a return to seller. I do FBM with Amazon provided customer service. In the past week I’ve received numerous refund emails for orders and various reasons. Emails stating package never received and emails saying package damaged in transit. Is this something that happens near holidays? My products are hard dog treats, the likelihood of them being damaged is slim as you could literally take a hammer to them a few times before they break. If anything the shipping container would get messed up before I’d ever think the product could. These reasons seem highly suspicious given the nature of the product and using Amazon to buy shipping with tracking.
