Hi KatieTB
I imagine the cats could pick up ticks from the same places hedgehogs pick them up from. So if there are ticks around the cats could pick them up from vegetation in the same way that hedgehogs can. But if your cats are fully treated for ticks, hopefully they should be ok. But, if you know there are ticks in the area, I would be inclined to check the cats for ticks regularly, even if they have been treated. Also make sure you don’t get any on yourself. I tend to either tuck trousers into socks, or wear wellies when walking through long grass where ticks might be present.
