I posted this on my facebook pag and also on the Fox Project FB page: a few months ago a fox chased my cat down the garden, luckily cat was faster than fox. Tonight while in garden, I saw a fox chasing a neighbour's cat! Bit worried now, one neighbour used to feed the foxes but she died 2 weeks ago, and they must be hungry. This isn't normal is it for a fox to chase healthy cats? It was a full grown fox and very fast
(I am still worried about our cats though, as one is elderly and not so mobile now).
This was their answer:
The Fox Project
The Fox Project It's highly unlikely that a fox would kill a cat. A fox recognises the cat as a fellow predator having that eyes at the front of the head thing going on, so will not see it as a source of food. Young foxes are often curious about cats, but once swiped they realise that the cat has an impressive set of razor sharp claws on the end of highly flexible front legs. Conversely the fox has relatively stiff legs in comparison to the cat with rounded claws designed for digging rather than fighting. No self respecting fox is prepared to risk loosing an eye by taking on a cat. Sometimes cats and young foxes develop a 'friendship' and are happy to coexist in the same garden, and some friendships have even been observed to extend to a game of chase.
That said, when cubs are young any mother will forget about her own safety in an attempt to defend her babies, so will try and chase a cat off. A lot of fox cubs are lost every year to cats digging them out of a den and taking them off as a hunting prize. Most mothers would move their cubs to another den site if a cat took too much interest.
If a hungry fox were to find a dead cat it would consider the carcass as a source of food. In the past this has been observed and some people have mistakenly thought the fox had killed the cat
