Ways to get cats used to cages and cat nests:
1 .. You can't put food and garbage boxes in it at the same time.
The cage needs to be big enough for the cat to move.
3. Teach cats to use automatic drinking devices.
4. You can put some cat's daily toys and old clothes or towels that smell like the owner in the cage or nest.
Cages and cat nests must be kept in warm places.
