Hi I am in urgent need of advice, i have recently moved into an apartment (rental with carpet)with 2 cavies both boys 9 and 14 years old. The 9 year old has adapted well now to the new toilet arrangment which is a courtyard with the door left open when i am not around. The 14 year is having issues. I am leaving the door open for them when i am not around and their water bowl is out in the same area. WHilst i have tried the constantly putting him out there and rewarding him when he goes go it doesn't seem to be getting through and every day i come home to a wee on the carpet which I am cleaning up when i get home for work. As an example this morning i put him out several times when we first got up and he kept coming back inside after i came out from the bathroom he had gone inside the house. The other problem i have is he is a barker. I have tried locking them out for the day only to come home to a note on the door with a complaint. On the weekend i bought a citronella collar which he doesn't seem to be the slghtest bit put off by he just barks through the mist unfazed. He is old but generally in pretty good health, he can go through the night without needing to go out at all. Any suggestion of how or what to do will be gratefully received.
