I agree with all the others! You say your local police say that cats are "feral" animals and therefore they can't do anything - that's total rubbish. If she were a very expensive pedigree cat, then the Theft Act would definately apply here, as she is your property!! That aside, she is STILL your property and you are within your rights to demand the police do something about it. The only reason she's still with this other person is that she's got her kittens and she won't leave them. Go and yell at the old bill again - I certainly would!!! Good luck & keep us posted, won't you? K xx
