Hi there! My name is XXXXX XXXXX I would be happy to help you with your question about Hercules.
Cats can certainly be trained, but they are more difficult to train than dogs, as they are solitary creatures (they do not adhere to pack statuses). This means that training a cat is more geared towards helping a cat find new learned behaviors, as they will not strive to please a "pack leader".
In short, cats respond best to positive reinforcement, meaning that they will perform an action in order to receive a reward. In this case, they have learned that if they make enough noise, your husband will come out to the garage to give them the attention that they need.
This is partially good, because cats do need interaction and attention from humans, and they need to have a way to announce their need (like when they are crying for food to tell you that they are hungry).
However, so long as they learn that crying leads to your husband going outside to pay attention to them, they will cry anytime they want attention.
Since cats are routine creatures, it might be helpful for him to set up several times a day that he goes out at the same time to spend time with the cats.
Initially, they will be crying for him to come outside and pay attention to them, but with a little patience, a good deal of ignoring the crying (and possibly some ear plugs), they will eventually grow accustomed to him coming out at the same time every day for attention, and they will cry less when they don't expect him to be there.
So what can be done if he is the problem and likes the interaction
So what's the answer?
So what's the solution?
