Cats have an instinct of covering their urine and faeces, at first the kittens may try to eat the litter, but slowly the idea will click. Reward him as soon as he does it right.
If you catch him toileting someplace else, pick him and bring him to the litter tray. Clean the area very well as the smell of urine may stimulate the kitten to go there again.
TRAINING
Litter trays should be removed after use and as necessary, either thoroughly cleaned or the soiled litter scooped out and replaced.
At least once a week, the tray should be emptied and disinfected using a cat friendly disinfectant which can be obtained from pet stores. Once his initial vaccinations are over you can allow him outside and he may go to the toilet outside.
HEALTH CARE
Vaccinations
Get your new kitten or cat checked out with a veterinarian and establish a schedule for his immunizations.
Kittens need to be inoculated at the age 9 weeks with a three-in-one vaccine that protects against Feline calicivirus and feline herpesvirus 1, which are responsible for the feline upper respiratory tract disease (cat flu) and the feline leukaemia virus.
The same vaccination is repeated at 9 and 12 weeks. At one year three months, they are due for a booster dose. Every year the booster dose should be repeated, for keeping your kitten healthy and protect them from infectious diseases.
