Sofi,
Hi. Just checking in to see how Gizmo is
coming along. My first experience with kittys
was bringing in two feral brother kitties.
About 10-12 weeks old at that time.They also
did the 'run & hide' routine whenever I
came into their room. They are now about
3 1/2 years old and own the whole house.lol.
Have you tried leaving a radio on in his
room.He would hear people's voices & soft music & might help him to relax even more.
Continued good luck to you & Gizmo...
which might help him
