I just wanted to add on behalf of the rescue you got Calvin from. I have dealt with this before too, feeling like they are not happy with you because you didn't choose the cat/kitten they picked for you. But, really they do understand that people are picking a cat for a lifetime and they want it to feel right and be the right fit for you and your existing cats at home. Because, if you don't feel good about the cat from the start, chances are it won't work when you get home, and they will be getting a call from you, which they don't want!! Sometimes, these adoption counselors, or even volunteers are so busy and have so much work to do that they come off sounding cold and leave the potential adopters wondering what they did wrong?? Well, nothing. They could be having a bad and very demanding day at the rescue as most are understaffed. So don't feel bad like you can't contact Calvin's rescue even though you got a new kitten from someone else. Truly, they don't mind and just move on to the next potential adopter. I am sure they would love to hear about how Calvin is doing with his new brother and would like a letter or picture for their bulletin board.
