Yeah, its any animal. You see it with dogs, cats, reptiles. For a while people would get rid of their cats during pregnancy because of fear of toxoplasmosis. But, I think more research on that has educated people on proper precautions if any need to be taken. Its amazing how love for a pet vanishes when a baby happens. Part of that is rightfully so. But then, my parents didn't get rid of their dog when they had me.
I live in a really poor, rural area of Iowa and sometimes there are cultural things related to poverty. Its a different attitude. Not always present in the poor, but often present when dealing with generational poverty. They get a pet and love it, but their life is already so ever changing that everything is just temporary with them. I'm not sure they mean LOVE in the same why that I mean it. Its more like, they want to love it and go through the motions of loving it, but life is hard so they'll just love it for now while they can and then move on when they have to. Its easy to let go because they've had to let go of many things over and over again in their life. Not that the wealthy can't be completely superficial and misguided too, but locally I just don't see a lot of pull yourself up by the bootstraps, get yourself a job, and education, make smart relationship decisions, kick the jerks out of your life, keep yourself out of trouble and make whatever it is work. They are willing to let life happen to them rather than taking control and making the life you want happen. Sometimes life sucks and you get married and your spouse becomes abusive or develops an addiction or mental/physical illness and everything in the world turns upside down. I get that, and in those cases it really is best for the pet to go elsewhere. Other times...its hard to change the attitudes and lifestyle people grew up with. People aren't always quite as self aware as they should be and maybe not getting love and stability and support from humans so they look to an animal which their lifestyle will not support keeping long term. Defense mechanisms and all. Not much you can do about that other than be there to help out when people need a new home for their pet and make the cycle end for that animal. And empower people with whatever skills they need to get themselves out of that cycle too.
I wonder if most charities will accept petfood?
