Integrating cat with 2 dogs

[jay30]

I have recently moved to Calgary (with a 2-year old cat, which has been by itself since 8 weeks) to be with my fiancée (who has a 3- and 5-year old English Setter - father and daughter, together for several years now.

We are having difficulty knowing how to integrate them (in her/their house). We have tried to keep them apart
and introduce them slowly, but the cat inevitably runs away.....the dogs following behind - and today with
some 'grabbing' etc. by one of the dogs of the cat - perhaps following hunting instincts....and protecting his property.

Can you offer us any advice on how to integrate these three?

Thank you

Jim
