I feel so sorry for you all. Sick kitties can cost lots of money. We took in the abuse cat in 2000 and he spews on a regular basis (one reason I feel he had > 2 homes in 18 months). We have done all the testing and changed cat food over and over again - even down to spoonfuls every couple of hours. Right now @ 3 meals a day, one snack time and one treat time. But alas - all systems a go and still he spews. I think it is more psychological - but we can’t afford a kitty psychiatrist.
Meanwhile - we are attracting cats from far and wide with the outside food. I have seen both of our neighbor’s cats in the past week. Plus others. Oh well - no one is skinny and if they hang out here - they aren’t getting run down or in trouble.
Obviously - your mommy kitty either had a terrible pregnancy or the genetics of the male - sucked big time. Too bad you can’t find him and get Alley Cat to neuter his worthless furry butt.
Oh, I know who he is. A real motley genetic slug. And I’m all for neutering him with my .22, once and for all. But she won’t let me.
Umm - we get rid of unwanted varmints with a havaheart trap and an old garbage can mostly full of h2o (for wild, we use much more) - I even went to a enviro wacko hug an animal today site to get their take on the most humane way to dispatch dangerous and bothersome wild animals - drowning is the most humane way to dispatch an animal quickly. I like your idea - but cities frown on using a gun (btw, we have varmint .22 rounds - intentionally) within their ‘limits’.
