AHA! Proof that people evolved from monkeys!!I once read about a study that has squirrels and I believe a monkey of some sort. The monkey learned the maze faster. Then they moved the animals away for 6 months or so. The squirrels picked up right from where they were no delay in running the maze. The monkeys had to relearn it.
Unfortunately the grey squirrels are the most destructive animal out there. The brown squirrels are more friendly and don't damage anything having their nest high up in the trees. The black squirrels are skittish and usually runaway from people, also have their nest in the trees. However the grey squirrels will dig a hole in your roof to get in where it is warm in winter to build their nest in the insulation, chew on the wiring and plumbing, and cause all kinds of damage. I've been to a Ladys $800K home where she had to hire a contractor to replace all the damaged insulation, an electrician to repair all the wiring that was chewed thru, and a plumber to replace the plastic plumbing line that was chewed. With the removal of the grey squirrel the bill for all that was $25,000. So when I see a grey squirrel out comes the rat traps and have-a-hart traps.Yes, you bet your butt squirrels are smart. There's not many ways stop them when they make up their minds they want something. We do enjoy watching the around our house (all gray squirrels because I "take care of" the reds.
My dad and I often discuss Thai topic about our dogs. It’s popular to give human characteristics to our house pets. Like saying they are happy. Who really knows?Like asking "how smart are people?". Animals perceive things differently from us and individuals vary.
