Our cat has finally sorted himself out, and is using the cat flap etc. Great.
Apart from the fact that all the neighbour cats want to come in! Our cat chased a couple of curious cats out. But there is another that comes in and eats his food. I can hear this cat munching away from the living room but my cat sits next to me and does nothing about it, so I have been chasing this other cat out myself.
It is long-haired and looks in good condition so not a stray (I wouldn't want to adopt it anyway)
Is there any way to keep it out other than magnetic catflap/collar?
