Has a fox come through the day flap?

[Dizzyhelterskelter]

We have 2 cats and, at night and when we go out, they are kept confined to the utility room which has a cat flap to the garden. We arrived home from a day out earlier & went to let the cats out of the utility room. They appeared distressed and, when we entered the utility room, were hit by a god awful smell. There was poo & wee all over the floor which surprised us as they have always been well toilet trained and have never had an accident in the house. There were also clumps of our neutered Tom cat's fur on the floor, indicating some kind of fight. Tom cat also stank of poo and had a slightly injured paw.

I assumed that another cat had come in through the cat flap but am now wondering if more likely a fox as I don't think a cat would poo like that. There was also more poo on the patio. We do have a lot of urban foxes around here.

I'm now really scared it will come back and harm my cats. Anyone had any experience of a fox coming through a cat flap. Is this even possible?

Tia.

Sorry cat flap - not day flap!!!

I would get a cat flap that only opens with a chip on the cats collars.
A fix used to come in ours if we left the door open

I had an adult fox try to get through our cat flap but it only got its head through. I was in the room when it happened and it was a shock. So I don't think an adult fox can get through a smallish cat flap. Could be an unneutered tom maybe?

Our cats are microchipped & I see you can get flaps that read the chip. Any recommendations?

We have the Sureflap and it's been great. If your cats are on the large size (like mine) we found it better to go for the pet flap rather than cat flap as its bigger. I've attached a photo of our flap so you can see the size compared to our cats. Sureflap also have great customer service if you have any problems.

Foxes stink. If the smell isn’t poo then it could be a Fox.
