Kitten behavior after spay surgery concerning

My 5 month old kitten was spayed on friday while she was in heat. She is now four days post spay. She is wearing an ecollar constantly because she goes for her staples every time I remove it. She has been sitting around, mostly in my lap sleeping. She hasnt really played or run around. She gets more active when I remove the collar though. She is eating normally but only when prompted. I have to prompt her to use the litter box but she is fine using it. Is she experiencing complications or depressed by her ecollar? Her incision is not red or swollen though there is some dried blood around the wound but no constant weeping

It's probably the e-collar. They usually make cats act funny.

I agree, she seems to act more active and rambunctious when I take it off.
