They do seem very needy mine are rarely in the green on their icon and always want attention no matter what traits they have. Also the dogs always want walking all the time and then their is a separate issue of how long the dog walks take a short walk will take my sims at least 4 sim hours. I know a lot of people complain about how buggy dine out is but I find cats and dogs just as buggy. A lot of the bugs I encounter in my game are from this pack and rarely play pets for this reason. I think the excessive neediness is a bug.
