Yes, it seems odd but its actually quite normal, lots of people get upset about animal suffering and not human suffering, I dont think we have a choice in the matter it depends how you were brought up as a child etc , depends on your life experience, were you brought up with children or animals or both have you had a child yourself, are your parents caring towards people or animals or both? etc etc etc
It seems odd because its not even our own species but it isnt odd because so many people are the same as me. Its normal.
I agree starving children are more important than starving animals for example but I cant change my feelings to care for children. Theres no on or off switch there's no choice. I care for cats and dogs and I dont care for humans children pigs cows or chickens.
I will add however that no LIFE FORM suffers more than the animals in China which include cats and dogs and in huge numbers, so in my opinion they are one of the most important causes to help in the world. That is where suffering is greatest in the entire world.
