2 -Change the cat litter box two times per week and scoop it out daily. If you have more than one cat, you will need to change more frequently, or even daily. Put a few boxes out to avoid accidents or if you have a multi-level home. Add litter box deodorizer at the bottom or baking soda for freshness and odor control.
3- In nicer weather, leave a window partially open so the cat can sit on the ledge. Just be sure the screens are secure and the cat cannot push his way out.
4- Have the number of your vet handy and know where you can take your cat if he gets sick after normal office hours.
5- Tag your cat. In other words, purchase a collar for him and put an identification tag on him with your name, address and phone number in case your indoor cat decides to venture outdoors. Wearing his collar all the time gets him used to having something around his neck.
6- Place a microchip in the cat for identification in case they get out and are lost. Pet stores, animal shelters and veterinarians will do this for an extra charge. This is optional but a sure fire way to identify a lost pet and get them back to their owners.
