New cat

[phesina]

I like to keep potentially-dangerous things like aluminum foil and saran (clear) wrap and plastic bags in a drawer or cupboard or other closed-off spot where the cat can't get at it but you can get it out when you need some.

Best wishes! And bless you and thank you for taking this sweet kitty in and giving him a home and loving him.

Fear aggression is activated by a cat who sees a danger that he or she cannot elude. Joint pain, dental malady, injury, and diseases are fair a few of the conditions that can cause torment and ensuing hostility when a cat is touched, or considers he or she may be touched, in an agonizing range.

You should bring him to the vet to be checked
