Daisy decided to visit Fluffy.
Hubby started giving treats after a few.
They were so close together. Fluffy seemed fine, and got to a point where he laid down. They we're within inches getting treats.. and to the point Daisy put her head through the rings or the gate.
Then they kind of sat there for a bit, quiet. Then he lunged and swatted at her through the gate. He didn't growl or hiss. He was doing so well. He tried doing it more than once, too.
Daisy just took a step back, then hissed and had a low growl after he was done.
this is totally normal and not a bad thing
