Why has my ex returned the cat I got him?

My ex cheated while I was in rehab I found out and ended things. He wasn’t viewing my WhatsApp status but after we broke up he stared viewing it and then just two days after the break up this is the first time he has texted he texts at midnight claiming I should pick the cat and his mom doesn’t want it anymore and assured me that he really wants to keep it but his mom won’t let him. Honestly I feel like this is an excuse am I being delusional or. If not what could be the real reason he is returning the cat?
