Is this a good idea to feed leftover food wastes to pets?

[BegoniaA]

I heard a SPCA in my town finding difficult to get donations from well wishers. So the stray dogs cats are under fed. I am planning to collect leftover food wastes i.e fish bones, fish heads, chicken legs, chicken bones from a few restaurents nearby and supply to this SPCA on daily basis. Is these type waste foods is hygenic and healthy for pets?

It can be if there not use to is. They have to pretty much babies so they can get use to eating whatever. It hasn't harmed any of the pets I know. My family had a beagle, and a boxer that ate everything. My husband and I have a pitt that eats everything. But we had them since puppies. When there wasn't any money to get them there food we would give them left overs. You would have to ask them if its ok what your doing. Good luck. And its a good thing what your doing.
