If they're available, may I suggest purchasing some Apple Air Tags?
They are, of course, useful for finding things like keys, luggage, cars, phones, etc. But there are some even more important uses to consider.
An Air Tag could be put onto your pet. There are collars that are specifically designed to hold an Air Tag. I host a regional Facebook page for lost pets. Every day, there are people looking for pets who have run away.
Also, consider putting an Air Tag inside your child's school back pack., in case something unfortunate might happen.
When not used inappropriately, the Air Tags offer some peace-of-mind, for relatively little money.
