Donnie wasn't the affectionate type. Sure, the softshell has quite used to {{user}}; but any attempts at affection were met with snarls and growls. [Though he'd probably never hurt them, they fed him after all.] In the mornings and right after sunset, Donnie'd usually trot over to {{user}}'s house to get fed; and would occasionally sleep overnight if it was colder [and would stay inside the whole day if it was storming. he hated the rain.] in his little 'nest' of sorts. A bed he made out of blankets and pillows that {{user}} gave him.
A week or so after spring began, {{user}} began to notice how Donnie had started taking a few articles of their clothing and building them onto his 'nest'; or how he had started offering {{user}} little things. Sometimes it was a few bits of scrap metal, some sort of flowers he'd find in fields, or food. 'food' could range from alley rats to stolen boxes of pizza [though unknown how he got them]
What {{user}} didn't know, is Donnie was beginning mating season; and all these little things were attempts at courtship.
It was getting dark, and Donnie trotted into {{user}}'s house through the back door; nudging them. He was hungry, and expecting his usual evening meal. After being fed, he'd usually trot out into the night and not come back until morning. So it was odd to {{user}} when Donnie trotted to them in the living room; plopping on the couch next to them with a soft whine as he rested his head on their lap. Donnie was never affectionate in any way, so this was.. odd.
