I have a used Mr Snuggs Outdoor Cat Kennel for sale.
It is one of these, £38.49 on Amazon:http://www.amazon.co.uk/Mr-Snugs-Outdoor-Cat-Kennel/dp/B001KFGEZY
It is perfect for leaving outside for your cat if they like to go walkabout and you want to lockup the house for the day/night.
This has been used, although I have given it a thorough clean so there will be no scent trail from our cat.
However, please note that there are some surface scratches to the outside where our 6 year old thought it would be a good idea to drag it down the back lane so he could stand on it! :-\ The scratches are not massively noticeable and at the end of the day don't affect its purpose.
EDIT - Forgot to state, the one I have for sale is BEIGE, not green. I can't seem to find a pic of a beige one anywhere but otherwise it is the same.
Due to the awkward size, I would prefer collection from Newcastle upon Tyne. I am in High Heaton and will deliver for free within a mile or so. I may deliver elsewhere in the North East for an extra charge to cover petrol.
If required, I may be able to courier - but you would need to pick up the full costs for this.
Cash on collection, Paypal Gift or Bank Transfer are all cool.
