During the summer I had two newly calved cows inside. Normally quiet but something triggered them to go mental, one having a go at me which made me do my jumping jack act sharpish. I was lucky. I don't know what triggered it but suspect a feral cat that appears from time to time. Suppose to a cow a cat appears as much a danger to its calf as a dog. Cows attacking dogs are a regular occurrence but cats?? Anyone had problems?
