I trapped a pregnant feral yesterday and had her spayed, I used a TruCatch fat cat trap. I have taken in many strays over the years but this is the first truly feral one I have dealt with. She is sitting quietly in her trap which is covered, she ate last night and a bit this morning, I am concerned because she has not peed or pooped, is this normal and due to stress? I was told to release her in 48 hours, seems to be a fine line between keeping her in a trap after major surgery and causing too much stress for doing so. Anyone experienced in TNR please comment.
