Hi, I TNR ferals, as,well as feed and shelter outside. I have 3 rescued kitties inside...2 I rescued as feral kitties in January about 8 weeks old. Monday they received shots, and were neutered. At first, one of them seemed to recover but now is just grazing and just came and sat on my blanket and peed on me. The other has been spacey since Monday...not sleeping, just grazing, and not playing with his brother. Before neutering, they were inseparable. Is this normal?
