As “cute” as this may be, please do not let cats and hamsters (or any prey animals for that matter) have direct interaction like this 🙃 cats are natural predators and can easily kill a hamster in a matter of seconds
the number of times I’ve heard of people dumping rodents, reptiles, and fish outside that they recieved as gifts... or cats/dogs that end up abandoned at shelters for the same reason is so sad. Animals may sound like a cute gift, but if it’s a surprise, you’re gambling their life
