Hi
Saw a thread about a cat that used to use a litter tray as a kitten, once it went outside would not go near it. Reply was sometimes once a cat toilets outside they will not use a tray again but the vet keeps asking me to keep mine in to collect a speciman. We have tried to keep him in and put up with all the crying but no way will he go in the tray. In the end one time he found a large brown bag and let rip with his loose stool (sorry to be graphic), we gave in at that point, vet does not seem to accept we have tried but failed to get him to stay in and use the tray. Any advice on what we could do to try and encourage him would be much appreciated.
