Hi
I have to 7 month old male kittens, who have been going out side since they were 4/5 months old.
The week before Christmas I got them castrated.
Since then two big cats have been sitting outside our back door, as of yesterday they have been fighting outside our back door, making noises like a baby crying. When we go out they instantly scarper off, our two kittens just sit and watch it all happening rather bemusedly.
One of the big cats has also at any opportunity been getting into our house.
What can I do about these two cats?
I don't know who they belong to.
TIA
