Wasted my effort installing wire-mesh at the kitchen window of blk *21 family... they keep opening the un-meshed side too. The poor kitten has a litter tray but there was now litter or even newspaper in it... just an empty plastic bowl. No surprise he preferred the kitchen sink to do his business...sigh! At least they keep him indoors now.
After I took the kitten home, the new female tabby appeared. I let her eat first and then tried to put her in the carrier... but she struggled and ran off, also saw another newbie... siamese-mix...
Twirly is eating well now, and no more vomitting...hope he will put on some weight soon.
