I don't think a binge alcoholic and perhaps even a binge alcoholic who is just starting on the road to recovery, should take on new responsibilities because they are quite likely to fail and upset people. They are more likely to hurt more people. Binge alcoholics are unsuited to taking on responsibilities. They are too unreliable. That is my experience in any case. Some constant alcoholics can manage and live relatively normal lives but they are very different to binge alcoholics.
Jane is a binge alcoholic and she has informally adopted a cat. The cat is a stray cat who has made her home with Jane. This is partly because Jane has been unemployed for a while and therefore is at home a lot of the time and the cat probably comes from a home where she is not particularly wanted or looked after properly.
But, when Jane wants to have a drink, everything flies out of the window. Nothing is in her brain except the desire to have a drink. Not even the health consequences of that drink will be addressed at that moment. Neither will she address the consequences that a binge will have on the people who love her and in this instance the cat who depends upon her.
If the binge becomes a big one it is quite possible for Jane to be out of action for almost 3 weeks, even more sometimes. These days she is very rarely out of action for more than about a week but that is long enough to cause problems for others.
I don't think, I regret to say, that a binge alcoholic is able to properly look after a domestic cat. Perhaps they may have some arrangements with other people so that when they are on a binge those people can step in and look after the cat. But alcoholics are secretive. They hide their alcoholism from others. They don't announce the fact that they're about to have a binge and be out of action for a long time.
They simply start drinking with a complete disregard, as mentioned, for everything else. When they have finished drinking and have recovered sometime later they are enormously remorseful, in my experience. They hate themselves for what they have done. They realise that they have hurt people and in this instance possibly put their cat in jeopardy but at the time they don't give a damn which makes them irresponsible and dangerously irresponsible.
Binge alcoholics, even those who are recovering, should think very carefully before they take on new responsibilities. They should focus upon what they know they can do what they have to do which is to get work and keep a job down and then keep their home in reasonable order; keep things simple to make sure that they can manage their lives.
