Recently, we adopted a one-eyed kitten named Wink.
We have a 13-year-old American Eskimo dog who is blind and diabetic. He gets jealous very easily, yet he accepted dear Wink right away. Amazing.
We let Wink immediately enter our home and we did not keep him locked in one room as the shelter suggested because in our hearts we knew he would be happier free ... and involved with everyone.
Cats and dogs can get along quite nicely if you trust and stay calm.
