Your rat squeaks when you pick him up due to protest (dislike of being held/startled), fear, pain, stress, or it might be a mild form of "chatting" if they're used to it, but always watch for other signs like hunched posture or puffed fur, which signal a vet visit for potential pain or respiratory issues. A single, short squeak can be normal, but prolonged squealing or shrieking, especially with other symptoms, warrants concern.

Can rats climb fences?

Yes, rats are excellent climbers and can easily scale most fences, especially if they have rough surfaces like wood, brick, or stucco, using their sharp claws and agile bodies to find footholds and grip onto textured materials, and even smooth surfaces aren't completely insurmountable for them. They can climb walls, pipes, and trees to access yards and homes, so height alone isn't always a deterrent, and burrowing under is also a common tactic.

Will sleeping with lights on keep rats away?

No, sleeping with lights on generally won't keep rats away long-term; they are highly adaptable and will find dark hiding spots (walls, attics) or simply adjust their activity to the light, so effective control requires sealing entry points, removing food sources, and using traps or professional pest control. While bright lights might initially startle them, rats quickly get used to consistent lighting if food, water, and shelter are available.
