Tactile contact with owners is very important for cats, but it must be timely.
For example, you should never touch a cat while it is eating.
The thing is that a cat may have an instinctive defensive reaction.
Simply put, your pet may think that you want to take away his food.
The consequences can be very dire, even including bites.
If a cat growls while eating, it is better not to approach it at all. Go to another room, let the pet eat in peace.
