My name is No Name - they are stray!

We rescued (literally) these two kitties on January 23rd. We went out for a walk with our dog, who is a Rottweiler, and heard a kitten in despair, we looked for the kitten who was crying and found it about 50 ft up a tree! When trying to coax the kitten out the tree, other neighbors commented that it had been up there for 2-days! We were dismayed to learn this! Anyway, we could not leave the kitty up the tree, so we hired a tree service and paid them to come get the kitty out of the tree. While waiting for the tree service another kitty popped out of a burrowed hole at the base of the tree. So, the tortie kitty was under the tree and the black kitty was up in the tree. Needless to say, we have them in our dog's crate, but our Rottie is struggling! We need to find a safe place for these kitties to go, we cannot keep them, and they are not safe with our rescue Rottie. They are as sweet as can be, very affectionate, litter trained and appear to in great health.
