It's also with mixed feelings I read this. Tigris doesn't seem very fresh, but the fact that he managed to jump all the way up in the cat tree shows he still has some strengh. It's been a stressful time for him going back and forth to the vet and being poked etc., so maybe he just needs some quiet time. Still, it's good that Siegmar is there with him all the time.

Was the chicken you gave him boiled? Have you tried giving him raw meat? Or raw white fish? Fister can't stay away from that, so perhaps it's worth a try.

I so hope Tigris will get better - I send him lots of kisses.

(((hugs)))
