Glad to hear they are doing so much better! You are doing a great job!

Simon is just like my boy Soni (pictured in my avatar icon thing)! Soni has been like that ever since we rescued him as a stray on my birthday of last year. He was four weeks old then and very tiny as well (a pound or so). He still can't meow. It sounds like he is saying "Mehhhhh" in a whisper. If you're willing to mimic that sound then he can hold a conversation as long as anyone!
