I'm asking for advice on behalf of a close friend who has recently adopted a rescued male cat. The new cat (quite elderly) is doing what cats do, ie trying to establish his territory over the younger, existing male cat in the house by chasing him, hissing etc.
This has been going on for about a month I believe and not really improving. My friend desperately doesn't want to return the new cat to the rescue centre, but obviously feels awful to her existing cat.
Any tips for helping them, errrm, bond?
(new cat btw is great with people and laydee cats, just not boy cats). Thanks.
