Hello, thank you for alerting me to our cat Theo (from Tatnell road!) i'm glad to say he is safe and sound back at home (us none the wiser of his adventures until seeing this post!). He is a very much loved cat but unfortunately very inquisitive, although he is microchipped we will be looking into the collar options due to his adventurous nature. Thank you so much for your concern and going to the trouble of posting.

P.s looks Ellie is a popular username!! ;-)
