GOOD IDEA with the vinegar!!! You are wonderful!!! So what youi are telling me is that I have to go and buy some more Carefresh? Boy I tell you. I told you THEY run the house !! I am the occupant working to pay THEIR bills. I will give them their litter box back...temporarily. Now when i go to Hawaii for 2 weeks in June, who is going to cater to them like I do? The vet wants them to stay there but I think I need to find a "pet sitter" because I don't think they will do good "caged" for 2 weeks. What do you think? Let me know when you get tired of me asking so many questions.
