Steps
1. Please don't just neglect the cat. The cat is fed up, starving, cool, afraid and the record goes on! If it's following you, then that indicates it needs your help. But since your studying this content then I will believe that you are going to help it.
2. Once you get the cat, take it to a vet! Have the vet examine it. This is especially useful if you have other kitties residing in your house, because most discontinued kitties are likely to be fed up, and can successfully pass as well as on to your other kitties. Sometimes it could be critical.
3. Carry it house. Buy resources for it - even if it won't be yours, it still needs resources. Carry it h2o, nourish it, get it a bed, cut its nails if required, everything that you would get with a frequent cat.
4. Get it vaccinated.
5. If you choose not to keep the cat, take it to the Gentle Community or your regional pet housing. WARNING! Create sure you TRY to take it to a no-kill housing. Those housing have less possibility of eliminating animals!
