Sorry, but what you've described looks, sounds and smells like a zoo. You've imprisoned a huge number of animals "because you like them". By doing so, you have effectively turned them into toys for yourself and your other animals (as the example of the dog torturing the hamster vividly demonstrates). This is an exploitation of animals.
<br>Had you not caged them, yes, there is a possibility that they might have been dead now, but there is equally a possibility that they would have been alive and enjoying freedom.
<br>Gnost: Probably the birds would already dye of freeze! They're not used to Portugal temperature!
<br>Svo: If so, what the hell are they doing in Portugal? Why aren't they in Brazil? Isn't it because some people like you support those who capture them, bring them to Portugal and sell them to people like you?
<br>Gnost: What do you want me to do? Buy a ticket plain and go to Brasil and free the birds? Why?
<br>Svo: My guess would be that you shouldn't perpetuate and reinforce animal slavery by buying animals. Boycotting pet-shops may be a start. Refusing to domesticate wild animals would be another step in the right direction. For instance, why on earth did you turn your dogs into your toys? Why do you wash the dog against her/his will? Why do you treat them like silly idiots, providing them with "lots of toys to play"?
<br>Gnost: I ask you: Do you prefer to have a dead dog, or any other creature beeing mistreated, or do you prefer that they stay at my place?
<br>Svo: Is there a third option?
<br>No, I don't want to see dead dogs and mistreated creatures, but I am not sure if your animals aren't being mistreated by you. To me, depriving someone of their freedom is the most evil thing is the world. And I am not convinced at all that they would have been dead/mistreated had you not imprisoned them in your room.
<br>Gnost: I didn't went all along until some jungle and catch some animal! I just picked up abandoned animals and some from some really bad pet shops!
<br>Svo: Don't you find something really really really sick about buying an animal as if she or he was an object, a commodity?
<br>Why did you pick up some of them? Were they ill or something? Are you sure they wanted you to pick them up? When I lived in Eastern Europe, there were many homeless animals running around, and they often came to my place for a "dinner", but it never even occurred to me to cage them. Well, I picked up quite a few creatures, but they were very ill for some reason, usually after they had been tortured by some sadists. But once they were well again, I always released them.
