I volunteer for numerous animal rescue agencies that all run as charities or non-profit societies. Giving money is not in the cards for me right now, but I have time that I can give. Right now, my wife and I are fostering for a local rescue and we have one diabetic cat, a 12 week old puppy and 4 year old chihuahua. In my experience, most animal charities are happy for any help that is given, it doesn't matter if it's money, time or materials, it all gets put to good use.
I must admit, I give more to animal charities, than to human charities, Probably in the proportion 3:1. I'm leaving a bequeath in my Will to animal charities as I think animals are more hard done by... It's not their fault they're in that situation. I wish I could adopt them all. When my mother passed away, I filled 5 garbage bags of towels, washers and sheets and donated them to one of the animal homes. They were very grateful.
I think I give more to animal charities than to Human ones.
I give quite regularly normally, but right at this moment have not given for several months at least as my own animals are costing me too much
I donate to several Animal Charities. In fact, I will be leaving most of my Estate when the time comes to Animal Charities... I mainly give to the ones where I have adopted dogs like RSPCA and Animal Welfare League. I also give to WSPA, Guide Dogs, Assistance Dogs Australia or any charity where humans can benefit from them...
I always donate to the animal shelters where I bought my dogs from. I also donate to WSPA and IFAW both international funds to help free animals and send them to safe parklands and enclosures. I have also made provision in my will for same.
