The questions of whether or not other animals are sentient, and what
“sentience” really means, have been with us for a long time.
I spent a lot of time reading studying animal behavior, via independent reading, online courses, and classes. Most of this information doesn’t cross over into what consciousness is. When you focus on behavior, then you pretty much stick with inputs, outputs, and consequences. This constraint is a best practice; a critical technique when it comes to solving problems.
