We get at least 3 different cats in our garden, however 2 of them only come in occasionally whilst this chap
is a frequent visitor. We thought at first it came in because we have 2 guinea pigs but we have also see him lurking behind some of our bushes near where the birds feeds and once we even saw him leap out trying to catch one.
Even worse was when a ginger cat nearly caught a collared dove who luckily managed to escape all be it without a few feathers leaving the cat hanging by its front paws from the bird table.
We have a dog who we let out the moment we see any cats but this doesn't seem to stop them especially the black one. We have thought about ultra-sonic repellers but we are not sure if it will effect the dog or the guinea pigs as well
