So today I got the trap, it's a fancy one, with a transfer ability in the back... so they'll neuter, tattoo, give flea and dewormer, test for FeLV and FIV (nervous about that, because aren't there false positives? If he is, I won't be keeping him around, he'll go to the cat sanctuary...
) and clean his ears. They'd also do vaccinations but if so he'd need boosters, and I'm not getting him back there in a few weeks for that so I'll pass on those.
I don't know when I'll do it, some time this week.
Today was a break through.
Last night I almost
could've sworn he arched and rubbed slightly against my gloved hand before hissing... today, it was obvious he was. Not only did he press against my gloved hand, he didn't hiss and let me do it gain a few minutes later, and all on his own he approached my gloved hand and gave it headbutts. He also rubbed his face against a drawer handle, I haven't seen him rub against anything in the room before. He still bites the glove though, so those aren't coming off.
It sort of makes me feel bad that I'll be trapping him the way I plan...
I hope he doesn't hate me after, but he probably will. However, he's still super food aggressive so if that's even remotely related to him not being neutered I want to have it done ASAP.
