I am equally a cat and dog person. I love my british shorthair cat, but she lives with my dad on the other side of the country, so I never see her. I really want to own a cat, probably another british shorthair or an exotic shorthair. The problem is my 5yo labrador! She is very boisterous and hyperactive for her age and although I've never seen her harm another creature, she barks at cats in the streets and tries to run over to them. I'm pretty sure she HATES cats. I couldn't live with myself if I did buy a cat and my dog hurt it, accidentally or otherwise. I'm just wondering if there is any way you can train a labrador to tolerate cats, even at 5 years old, or have I left it too late?
