Thanks to everyone who has responded. I learn so much from everyone on this forum!
Even though I can say I would never leave anything behind for someone to clean up I know that there are others that would. I am going to go ahead and send the letter and just request that they consider allowing pets if they are in an enclosed carrier.
In a million years, I would never have guessed that I could get so attached to these beautiful babies. I love the smiles that they put on people's faces when you have them out in public! Lexi and Cricket sure make my day and I guess I just want to share it! Again, thanks everyone for taking time to write!!!
