OMG mistersmom that is so caring to rescue the catapillars, I thought I was the only one that did that sort of thing! I used to rescue butterflys or moths that I found with tattered wings that could no longer fly and keep them in a fish tank and pick flowers full of nectar for them when I was younger.
I also hand reared an orphaned baby (wild) rat a couple of years ago, her name is Pumpkin and I still have her because I kept her as a pet in case someone hurt her if I released her! She is around two and a half years old now and is blind in both eyes (because of her age) but she is completely happy and knows her way around her cage. She is also as affectionate as any cat and loooooves a scratch under her chin and will roll onto her side so I can stroke her belly. So many people think I am crazy for rescuing a wild rat when they are considered 'pests' but Pumpkin is no different to the domestic rats in the pet shop. She was barely a week old when I found her crying in our car she because she had either been abandoned or her parents had been killed. I just couldn't stand her suffering so I did what I always do in a situation like that, I do everything I can to help.
I have also hand raised a couple of house/wild mice because a kookaburra killed their parents. I named them muffin and cupcake and also kept them as pets, they were every bit as tame and affectionate as Pumpkin. I have hand raised over 100 orphaned birds both wild and domestic, cared for wild lizards that had various injuries until they were well enough to be released again, rescued so many wild birds and animals that have been hit by cars/attacked by pets or whatever and nursed them back to health and released them again. The list goes on. Pretty much every pet that I own is rescued that includes 200+ birds (mostly budgies), my horse who is terribly dangerous and was sent for slaughter but was rescued at the last minute and I took her on when the next few owners could not control her. My cat Oscar who I have now owned for 5 years, my mice and rats are rescues. In fact the only animals that I have that weren't really rescues are the bettas but considering the rubbish that most (not all but most) pet shop staff tell people and the conditions that they are often kept in as a result I guess in a way.........
Just thought I would share all that, oh and of course I am vegan too so basically I spend my life doing everything that I can to make the world a better place for animals
