How discouraging for you. If I understand you correctly, the family you placed them with promised they would get the boys neutered and then didn't. And they made the boys outdoor cats instead of indoor only which they'd promised you?

Possibly, due to the adopting family's not following through on their word, you didn't have a real effect on these two boys other than giving them a home. What about the other two in the litter? Are their lives better as a result of your intervention?

Several of the members here that do rescue or raise litters have a contract they have the adopting familys sign before they release their babies. Maybe that would help you in the future?

It's tough to put so much time, effort, love, and all into helping a furkid and feel it's for nothing. Please don't let it stop you from acting in the future. You might just want to put a bit more into the evaluation of the offered home next time.

I've got a soft spot for orange tabbies myself. [Okay, I know they are red, but they look orange to me. ] It must hurt to see them getting so much less than you were promised.
