Jack russell jealous of new kitten
We have a pet jack russell for five years now and he has been our only pet. The other day we found an abandoned kitten in the garden and we gave it milk and its gotten very quite. The children love the kitten and always feed and we want to keep it. However our jack russell has to be tied as he constantly barks at the new kitten and when we let him near it he started trying to attack it. I think he is very jealous about the kitten. I was wondering what we should do about it and how to get him used to the new kitten as we want to keep it . Thank you.
