LOL.. I think she had her eye on Alice.. She suffers her. Alice is the new one to the family..and moves very fast.. ;)

Alice was always stuck to my ankle, and loved to play.. She's a sweety..

Kearen is amazingly fast for a 24 pound fat cat.
If Penny has been there for longer, then she is the 'alpha animal' in the house and will not suffer other critters nosing into her turf kindly.
Unless she can find some use for Alice, she'll see her as an interloper.
(OTOH, she might end up seeing Alice as 'her' dog. My father's cat NiMh saw our dog Tiny as 'his' dog. He still likes to be walked as if we're walking the dog, he seems to miss her.)
