Jackson teaches that cats are territorial, needing spaces within homes to call their own and that they send signals when they no longer desire petting, a condition he refers to as "overstimulation."
", he said that cats become hyper aware of the weapons they have left, going straight for back claws (if these have not been removed) and teeth, because that's what they have to fight with.
Most cats need exercise to release excess energy in a positive way; toys and play with owners are outlets Jackson encourages.
In multi-animal situations, Jackson creates barriers in homes to divide the space into areas which the animals can claim as places of their own.
