If the animal (e.g. cat) stays at home, you can also check where it's hanging out from your holiday destination, yes. Provided you have data access on your mobile phone abroad (WiFi, data roaming, etc.).
In our case, it is sometimes a bit inaccurate (about 10m off) or gives a completely wrong location (about 1km off), but after a few minutes the error is usually corrected. However, the network coverage for the iot network is not particularly good in our area either.
By the way, here you can see the network coverage for Switzerland for the GPS tracker
